Customer Service Comments for Performance Reviews — Expert Guidance and Ready-to-Use Language

Purpose and principles

Performance review comments in customer service should communicate measurable outcomes, observable behaviors, and a clear path forward. Reviews are not just retrospective assessments; they are documentation that supports coaching, compensation decisions, and legal compliance. Well-crafted comments reduce ambiguity: instead of “good communicator,” say “achieved a CSAT of 89% in Q2 2024 and reduced average hold time from 4:10 to 2:55 minutes.”

Use objective data where possible and pair it with specific behavioral examples. A useful framework is Situation-Behavior-Impact (SBI): describe the situation, the exact behavior you observed, and the impact on metrics, customers, or colleagues. This approach creates defensible, actionable comments that employees understand and can act upon.

Structure of effective performance review comments

Each comment should contain three elements: context, evidence, and recommended next steps. Context answers “when” and “what” (e.g., “during the busy holiday period, Nov–Dec 2023”). Evidence is numeric or documentary (tickets handled, CSAT, NPS, FCR). Next steps are time-bound and measurable (e.g., “complete Advanced Product Training by 30 Sep 2025 and achieve a 5% improvement in FCR within 90 days”).

Keep language precise and avoid vague adjectives. Prefer “resolved 120 tier-2 tickets with a 78% first-contact resolution rate” to “handled many tickets well.” When writing development-focused comments, include explicit success criteria, such as “shadow senior agent for 10 calls/week for 6 weeks and reach an AHT below 7:00 minutes while maintaining CSAT ≥ 85%.”

Quantifying performance: KPIs, benchmarks, and how to cite them

Use standard customer service KPIs and cite internal or industry benchmarks when available. Typical KPIs to reference include CSAT (Customer Satisfaction), NPS (Net Promoter Score), FCR (First Contact Resolution), AHT (Average Handle Time), and SLA adherence. For example, an acceptable regional target might be CSAT ≥ 85%, FCR ≥ 70%, AHT ≤ 8:00 minutes, and SLA adherence ≥ 95% during business hours (Mon–Fri, 09:00–18:00).

When you reference benchmarks, give the source and date if possible: “CSAT 82% (2023 internal benchmark), compared to Zendesk industry median 2022–2023 ~80%.” If you lack external sources, use rolling 12-month internal medians to avoid snapshot bias: e.g., “12-month median CSAT = 84%, Q1–Q2 2024 average AHT = 7:12.” Document the data source (ticketing system, Workforce Management export) and the extraction date to preserve auditability.

• Key KPI targets to use in comments: CSAT ≥ 85%; NPS ≥ 25; FCR ≥ 70%; AHT target by tier: Tier 1 ≤ 6:30, Tier 2 ≤ 12:00; SLA adherence ≥ 95% during business hours.
• Use time windows: weekly trends (7–14 days), monthly comparisons (MoM), and trailing 12 months (YoY). Example: “Improved CSAT MoM from 78% (May 2024) to 85% (Jun 2024), 7-point increase.”
• Attach absolute counts where relevant: “Handled 1,240 tickets from Jan–Jun 2024, with 320 escalations (25.8%).”

Ready-to-use comment templates and phrasing

Below are concise, professional comment templates you can adapt. Each line is crafted to include context, measurable evidence, and a recommended next step so comments are complete and actionable. Use templates verbatim where appropriate, but personalize names, dates, and numbers to reflect the individual’s data.

These templates cover common review outcomes: exceeding expectations, meeting expectations with growth areas, and needing improvement. Save them in your HR or team review library and pair with the employee’s dashboard extract (export CSV of tickets, CSAT, AHT) as an appendix.

• Exceeds expectations: “Consistently exceeds targets — Q2 2024 CSAT 91% (target 85%) and FCR 78%. Took initiative to lead the ‘Returns process’ enhancement on 2024-04-15; resulted in 12% fewer escalations. Recommend formal recognition and consideration for Team Lead role; propose 30% shadowing of TL duties for 3 months starting 2024-10-01.”
• Meets expectations with improvement plan: “Meets core metrics: CSAT 84%, AHT 7:05. Opportunities: FCR is 62% vs. target 70%. Action: enroll in Advanced Troubleshooting course (course code CUST-302) by 2024-09-15 and complete 10 coached calls/week for 8 weeks. Expect to reach FCR ≥ 70% within 90 days post-training.”
• Needs improvement: “Has not met SLA targets in 3 of the last 4 months; SLA adherence average 88% vs. 95% target. Observed delays in ticket triage during peak hours (12:00–16:00). Required actions: adjust shift availability to cover peak hours, complete time-management coaching by 2024-08-31, re-evaluate after 60 days. If no improvement, escalate to formal performance improvement plan (PIP) per HR policy (PIP duration 90 days).”
• Customer feedback focused: “Received 23 direct positive comments between Jan–Jun 2024 (sample attached). One negative comment (2024-05-03) noted communication clarity. Recommendation: review ‘Effective Empathy’ module and practice phrasebank for 30 minutes/week; retest via recorded calls for 4 weeks.”
• Team/mentorship contribution: “Volunteered 18 hours to onboarding new hires in Q1 2024; new hires’ ramp time reduced from avg 6.5 weeks to 4.2 weeks. Recommend formal mentor designation and $500 one-time stipend for mentoring in FY 2024 budget line 2.3.4.”

Coaching, development plans, timelines, and follow-up

Create 30/60/90-day plans with specific deliverables and measurable checkpoints. Example: 30 days — complete training and shadow 10 calls; 60 days — demonstrate target AHT and maintain CSAT; 90 days — sustain improvements with minimal coaching. Document checkpoint meetings with dates and sign-off: e.g., “Checkpoints: 2024-07-15, 2024-08-15, 2024-10-15.”

Track progress in your LMS and ticketing system. Use observable artifacts for sign-off: training completion certificates, recorded call evaluations (rating sheets), and exported KPI reports. If compensation adjustments are tied to outcomes, state the trigger explicitly (for example, “eligible for up to 3% merit increase if CSAT ≥ 86% and FCR ≥ 72% by review date 2024-12-31”).

Common pitfalls, legal considerations, and record-keeping

Avoid vague or subjective language that can be interpreted as discrimination. Stick to documented behaviors, dates, and metrics. Keep all review documents and supporting evidence (ticket exports, call recordings) stored securely with HR — include links or reference IDs, not just verbal statements. Example: “See ticket export ID TCKT-20240601-034 and call recording CR-20240603-112 for examples.”

Follow local labor laws and company policy for disciplinary language; when a PIP is invoked, include clear improvement criteria and consequences. Retain copies of the review in the employee’s HR file for at least the period required by your jurisdiction (commonly 3–7 years).
