Call center quality assurance (QA)
Most QA programs review just 1–3% of calls. Here's how to close the coverage gap and coach every agent.
What is call center quality assurance (QA)?
Call center quality assurance is the set of processes used to monitor, evaluate, and improve how agents handle customer interactions. During the QA process, you’ll review the way your team handles customer interactions, gaining insights into customer satisfaction levels and identifying agents who need extra help. It’s about spotting problems and making the necessary adjustments to improve service quality.
Traditional QA relies on sampling: supervisors review a small slice of calls and use those findings to conclude overall performance. Manual QA reviews only 1–3% of calls, meaning 81% of agents report that most of their conversations are never reviewed at all. Modern QA programs close that gap through automation, making complete interaction coverage the baseline rather than the exception.
QA vs. QC (quality control) and QM (quality management)
When looking into quality assurance for call centers, you'll probably come across a couple of related terms: quality control (QC) and quality management (QM). What's the difference?
Call center QA monitors and improves customer interactions to maintain performance standards and hit KPIs. In an inbound call center, for instance, QA ensures agents provide consistent service quality for incoming customer inquiries while meeting critical response benchmarks. QC, meanwhile, tracks operational activities: agent attendance and punctuality, the efficiency of internal workflows, and similar measures.
QM is sometimes used as a synonym for QA, but can also refer to the combination of both QC and QA in a call center.
Call center quality assurance vs. contact center quality assurance
Let's address the call center vs. contact center distinction, since it causes real confusion.
Most businesses today interact with customers across many channels. A department that handles those multichannel interactions is a contact center, which is the more accurate term. "Call center" is the name from the days when phone calls were the dominant customer service channel.
"Call center" is such a ubiquitous term, though, that while it's often no longer technically correct, it isn't going anywhere. When people discuss quality assurance in contact center operations or call center QA, they're generally referring to the same thing. The two terms are broadly considered synonymous.
Why is QA important in a call center or contact center?
QA is central to any contact center because it's the only way to continuously improve the service you offer, and customers will always expect better. Here's how QA, done well, improves the way your call center operates:
Strengthening your support team
QA helps you find areas of improvement for your team and lets you build effective coaching and training sessions around specific, documented performance data rather than impressions.
Improving customer experience
With a stronger team, your call center provides better assistance. That results in higher interaction quality and better retention. Effective QA also helps ensure a consistent customer experience regardless of the channel customers use.
Refining business goals and processes
With consistent QA, you'll anticipate customer needs and adjust your processes to meet them.
The stakes here are rising. Gartner predicts that agentic AI will autonomously resolve 80% of common customer service issues without human intervention by 2029, reducing operational costs by 30%.
Contact centers building a strong QA foundation now, one that runs on complete interaction data rather than samples, will be better positioned to govern and direct AI-assisted operations as that transition happens. Investing in contact center automation without a corresponding QA infrastructure to evaluate it is a significant gap.
The benefits of call center QA
Call center quality assurance brings real benefits to your business:
Better customer satisfaction
If you deliver consistency and quality across all interactions, you'll drive higher customer satisfaction.
When callers don't wait in lengthy queues and receive efficient, friendly assistance, their customer satisfaction (CSAT) and Net Promoter Score (NPS) scores will be higher. They'll stay loyal, recommend you to others, and give you long-term business relationships worth protecting.
Improved first contact resolution rates
Call center QA means giving agents effective coaching and the right tools. They're better placed to handle issues quickly, resolving them during the first interaction wherever possible.
With proper training and technology, callers won't have to repeat their information to multiple agents or call a second time about the same issue. Whichever agent takes the call, they're equipped to handle it.
Enhanced agent performance and skill development
A key component of call center QA is ongoing coaching. Quality monitoring helps managers accurately assess agent performance, identify who needs to sharpen their skills, and deliver personalized feedback and training where it's needed.
When agents feel supported and have real opportunities to develop, they're more motivated and engaged. Happy agents = happy customers.
Shorter call handling times and lower operational costs
By using QA to measure and improve metrics like first contact resolution (FCR) and average handle time (AHT), you reduce the time agents spend on each call or issue.
Shorter calls cost less. Agents move to the next customer faster, handling more per shift. That operational efficiency compounds into real cost savings.
What are some challenges of call center quality assurance?
Quality assurance in a call center is necessary, but it comes with real difficulties. Here are the common problems QA specialists and compliance managers encounter:
- Data volume: The sheer number of interactions makes comprehensive manual review impossible, which is why most QA programs end up reviewing only 1–3% of calls. That sampling gap leaves most agent behavior unscored and most coaching opportunities missed.
- Data misinterpretation: Without consistent scoring frameworks, different reviewers often evaluate the same interaction differently.
- Time demands: Monitoring and analyzing calls, emails, or chats manually is resource-intensive. It pulls QA specialists and supervisors away from higher-value work.
- Agent pushback: Some agents are uncomfortable with monitoring, particularly if the process feels inconsistent or punitive.
- Outdated software: Legacy QA tools often lack speech analytics, real-time alerting, and automated scoring, creating manual bottlenecks that slow feedback cycles.
AI call center technology makes the biggest difference by closing the sampling gap. Automated QA tools score 100% of interactions consistently, removing the coverage problem and reviewer bias in one move.
It's also common for businesses to outsource their call centers. That's a valid option, but it comes with its own QA challenges.
BPO (business process outsourcing) companies have different definitions of quality. When choosing a BPO, make sure they're meeting your standards. While specific metrics depend on your needs, keep these general factors in mind:
- Reliability: Can the BPO deliver on its expected KPIs?
- Efficiency: Can the BPO resolve customer concerns effectively?
- Promptness: Can the BPO maintain deadlines and keep to a consistent schedule?
Call center quality assurance best practices
How you approach QA depends on your specific business needs. Here are the practices that apply across the board:
- Monitor goals and performance consistently
- Decide who's responsible for reviewing calls
- Use the right call center quality assurance software
- Hold regular, personalized coaching sessions with your team
- Establish a consistent penalty/reward system
- Develop a customer-centric culture
Monitor goals and performance consistently
QA in contact centers isn't a "set it and forget it" process. Don't create a QA framework and then sit back, thinking your job is done. Effective QA is iterative. You need to keep your call center ahead of changing market trends, shifting customer expectations, and competitive pressure.
When you set up your QA program, define your KPIs and how and when to track them. Stick to that plan. Regularly monitor calls and other customer interactions and look for ways to improve.
Consistency matters. If more than one person reviews customer interactions, make sure they're all evaluating calls in the same way. Always listen to the entire call to get the full picture.
When there's a problem, drill into the root causes. Document your analysis so the same mistake doesn't recur. Periodic audits surface potential issues before they compound.
Don't hesitate to update your goals. Call center operations are fluid, and you may find that objectives become less relevant. Adapt accordingly.
Decide who's responsible for reviewing calls
For consistency, everyone needs to know who owns what and who to report to.
Appoint someone to head the QA team, with ultimate responsibility for making sure processes are followed and quality standards upheld.
Call center managers are often involved in QA because they have close relationships with their agents, but managers have other tasks that compete for their time. QA specialists, by contrast, can devote all their attention to quality assurance as their top priority.
You can also involve individual agents. Peer-to-peer quality monitoring helps agents learn from each other, and it's especially useful for new hires. Encouraging agents to review their own calls and identify strengths and weaknesses makes them more accountable for their performance.
Set a timetable for call monitoring and stick to it. If you're using manual methods, you might look at a certain number of calls per day, per team, or per agent.
Use the right contact center quality assurance software
Monitoring performance across your call center used to be genuinely onerous. Call center managers could only monitor agents' calls by sitting next to them as they handled them. Modern contact center quality monitoring software changed that.
The right software records all calls automatically and gives you a range of monitoring options. You can also reduce the time spent on manual QA reporting.
AI has expanded what QA software can do. The right platform doesn't just record interactions; it scores them, flags patterns, and triggers coaching, all without waiting for a supervisor to manually review a sample. That's the difference between a QA program that captures call center productivity gains and one that only documents them after the fact.
Hold regular personalized coaching sessions with your team
QA isn't all about software and data. There's a human element your agents and teams represent, and it shouldn't be overlooked.
Train agents consistently so they have what they need to perform. You'll have already chosen agents with the right skills: empathy, problem-solving, clear communication. But you can always sharpen those skills and train them on new tools and workflows.
Built-in analytics help you pinpoint individual strengths and weaknesses. Build your coaching sessions around those findings.
Types of training
There are various models for agent training. Some people respond better to classroom-based sessions; others prefer one-on-one training. Remote agents can complete online modules.
Train agents on common customer personas so they can adapt their tone and conversational style accordingly. They'll also need to develop active listening skills, backed by customer sentiment analysis from your AI tools. And of course, they need in-depth knowledge of the product or service the company provides.
Establish a consistent reward system
You also need to reinforce standards. Incentivize good practice and discourage bad habits across your teams. Offering rewards like extra time off or a cash bonus to top-performing agents is one approach.
Gamification incentivizes agents to perform. Displaying a leaderboard that's transparent about scoring can inspire self-improvement. Give constructive feedback to everyone and let them know they're valued.
Consistency and fairness are what make the system work. Accuracy in how you measure performance is non-negotiable.
Feedback works both ways
Be open to receiving feedback from agents when they disagree with your assessment or when there's a discrepancy between their self-review and the official one.
Talk through the issue. If an agent thinks they acted correctly in a certain situation, find out why, then suggest how they could have handled things differently.
Encourage agent participation when discussing process improvements. The people who follow these processes every day are best placed to spot obstacles and gaps. Use metrics to show agents how their ideas are working.
Develop a customer-centric culture
Successful call center QA runs on a customer-centric culture. This starts at the top and requires everyone to understand why customer satisfaction drives the business.
Everyone needs to know that the call center is a vital part of a larger operation and that service quality matters to the business as a whole. Your QA insights are also useful for sales reps, marketers, and product developers.
With a customer-first attitude and the right tools and processes to support positive interactions, improvement in quality assurance metrics will follow.
Components of a call center quality assurance process
What does call center quality assurance look like day-to-day? It includes both automated and manual elements that combine into a coherent process:
Automated QA
Automated QA is where modern contact centers gain the most ground. By scoring every interaction automatically, QA teams move from sampling 1–3% of calls to analyzing 100% of them. That shift changes what's possible: you get consistent scoring without reviewer bias, faster feedback cycles, and a far more complete picture of agent performance and customer experience.
Automated tools use speech analytics and natural language processing (NLP) to detect customer sentiment, flag objections and competitor mentions, identify compliance risks, and surface coaching opportunities. They can alert managers in real time when a call goes off-track, so supervisors can intervene before a situation escalates.
Human judgment still matters for complex interactions. AI quality management ensures QA teams have data on every interaction, not just the sample they had time to manually review.

Manual QA
Manual review still has value, particularly for complex interactions and nuanced customer feedback.
In a business with high call volumes, humans can't review every single call. This is why call centers use sampling: taking a subset of interactions, assessing them, and using those findings to get a picture of overall performance. Used alongside automated QA, manual review retains its value for the interactions that require nuanced human judgment.
Call monitoring
Call center quality monitoring involves QA specialists or supervisors reviewing a sample of calls. They use pre-defined criteria to assess agent performance: whether the agent stayed professional, adhered to a script if required, and demonstrated thorough product or service knowledge. They also evaluate customer satisfaction levels.
Samples are often random, though there are times when supervisors focus on specific call types, calls with dissatisfied customers, or conversations with new agents, for example.
Quality scorecards
Quality scorecards are a consistent framework for assessing agent performance during customer interactions. QA specialists assign a numerical score to each evaluation category and add them to an overall total.
Agents are evaluated on things like the greeting they gave the caller, whether they demonstrated active listening, and how well they resolved the issue. Scorecards often assess script adherence, account verification, and post-call documentation.
Feedback and coaching
QA specialists review scorecards and findings from monitored calls, then provide feedback to agents, highlighting what they did right and where they can improve. Where your call center platform has a live coaching tool, supervisors can intervene in difficult calls to help turn them around.
Call calibration
QA teams hold regular calibration sessions to keep evaluation and scoring practices consistent. In these meetings, they review recently monitored calls and agree on standards so all calls are assessed the same way.
No matter which QA specialist reviews a call, the agent will be judged on consistent criteria and receive the same feedback.
Quality assurance reporting
Beyond giving feedback to individual agents, QA specialists produce regular reports to share with management. These reports summarize agent performance data from call monitoring and scorecard results, including analysis of key metrics. They also highlight call quality trends and areas for improvement, helping call centers deliver the right training and implement the right processes.
Call center quality assurance metrics
Whether you gather data manually, through automation, or both, QA metrics play a central role. These are quantitative measures of interaction quality that make it easier to assess performance and track changes over time. They include:
- Efficiency and agent performance metrics: first call resolution (FCR), average handle time (AHT), average speed to answer (ASA), and call transfer rates
- Customer feedback metrics: customer satisfaction score (CSAT), net promoter score (NPS), and customer effort score (CES)
Tracking these metrics helps managers spot bottlenecks, measure improvement, and evaluate how QA initiatives are actually performing.
Important note: Contact center quality assurance metrics
As mentioned, call center and contact center quality assurance are typically considered the same thing. In the area of metrics, there are some minor practical nuances. Where first call resolution is a call center QA metric, first contact resolution is the corresponding metric in a contact center.
What KPIs and metrics should you measure your agents against?
Given the wide range of QA metrics available, you need to decide which best fits your organization. There's no one-size-fits-all answer.
A call center handling hundreds of calls per day might focus on average handle time (AHT). Another might prioritize first call resolution (FCR) or CSAT scores. The best call centers aim for a balanced mix that accounts for both speed and service quality.
How to monitor, measure, and analyze the metrics
Early call centers relied on manual methods: paid surveys, custom scorecards, telephone mystery shoppers, manual recording, and monitoring.
Modern AI-powered quality management and analytics tools collect data automatically and present it in clear summaries. These tools form the backbone of effective workforce engagement management.
You can use AI for supervisor monitoring in real time, map the customer lifecycle, and collect data at every touchpoint.
How to improve contact center quality with your data
Once you have the data, decide what it tells you about improving customer service.
Do your agents have a high AHT? They likely need training on the specific interactions driving up handle time.
Do your customers prefer other channels? An omnichannel contact center solution is the right move.
Streamline your QA with the best call center quality assurance software features
Smart QA software improves your processes and boosts satisfaction scores and customer retention. Here are the specific capabilities worth evaluating:
AI interaction scoring (100% coverage)
AI-powered scoring analyzes every interaction automatically and consistently. The score reflects actual performance data, not a supervisor's impression of the calls they happened to pull. Full coverage means no blind spots, no survivorship bias in your coaching program, and no undiscovered compliance risks.
Custom scorecard configuration
Your QA program should reflect your business standards, not a generic template. Look for software that lets you adapt scoring criteria, weight different evaluation categories, and configure rules that match your specific compliance and service requirements.
Real-time agent coaching triggers
Automated QA is most valuable when it feeds coaching in real time, not just in a weekly debrief. Platforms that surface coaching suggestions during or immediately after an interaction compress the feedback loop, so agents can correct behaviors before they become habits.
Trend and topic analysis
QA software should surface what customers actually talk about, not just how well agents responded. Trend analysis identifies recurring objections, common escalation triggers, and product feedback themes. That intelligence is useful well beyond the QA team.
Competitor mention tracking
Speech analytics can automatically flag when customers reference a competitor by name. That data feeds directly into sales and product conversations and gives QA managers a heads-up on competitive pressure before it shows up in churn numbers.
CRM and telephony integration depth
Standalone QA tools that don't connect to your CRM or ACD create data silos. The right software integrates interaction data with customer records, so QA scores exist in context and coaching conversations can reference the full customer history.
Compliance monitoring
Regulated industries need QA software that monitors for required disclosures, flags prohibited language, and generates auditable records. Look for configurable compliance rules that go beyond generic sentiment detection.
Automatic call recording and monitoring
Recording calls lets managers review and score them later and identify common trends. Always inform customers that you're recording for quality assurance purposes and get their consent.
Live agent assist
Live agent assist tools give agents the information they need to resolve issues quickly. As well as pulling answers from a knowledge base, these tools can suggest the best responses to difficult questions or objections, directly supporting FCR improvement.
Call summaries
Automatic call summaries and transcripts save significant time on post-call workflows. Agents focus fully on the customer without taking notes; supervisors can review interaction highlights instantly without listening to full recordings.
