You just pinned anchors and now your Senior Chief is standing in your doorway: "I need you to write up Chief Petty Officer Harris by Friday — INSURV is next week and I don't have time." You've written EVALs before. Good EVALs. But Harris is an E7, and you have a nagging feeling that the formula you used for petty officers won't cut it here.

Or maybe you're a Master Chief who's been writing CHIEFEVALs for years, watching your chiefs plateau at Must Promote while the ones written by your counterpart across the waterfront keep getting selected. The write-up is the difference — and the gap is almost always in how the block opens, how the bullets are framed, and whether the closing actually advocates.

This post shows you what works, with weak and strong versions of every section so the delta is obvious.

Why CHIEFEVAL Raises the Bar

The CHIEFEVAL and the standard EVAL share the same form — NAVPERS 1610/2. The difference is what selection boards expect to find in it.

For E1–E6, great EVALs show technical proficiency, mission impact, and measurable results. That formula still applies for chiefs, but it's the floor, not the ceiling.

For E7–E9, selection boards look for three things that rarely appear on petty officer EVALs:

CPO Mess leadership. Did this chief actively shape the enlisted culture at their command? Mentoring E6 and below, running advancement programs, representing the Mess — these belong in the performance bullets, not a footnote.
Program ownership. Not task execution but owning a readiness domain, a training program, or a cross-departmental function.
Command-level framing. Even a chief running a small work center should be writing impact in terms of the command's readiness, the strike group's capability, or the fleet's bench — not just their eight-person shop.

Chiefs who write E6-flavored bullets with an E7 name on top leave boards underwhelmed, even when the underlying performance was excellent. The framing is the job.

The Three Parts of Block 41

Block 41 is the reporting senior's comment block — the section that does the heavy lifting in any selection board review. Competitive CHIEFEVALs follow a consistent structure:

Opening statement. One to three sentences that establish who this chief is and at what scale they operate.
Performance bullets. ALL-CAPS headline (five to eight words) followed by supporting detail with specifics.
Closing statement. Direct, unambiguous advancement recommendation.

Every reporting senior knows to include all three. The question is execution.

Opening Statement

The opening is the first impression. Selection boards read hundreds of CHIEFEVALs in a sitting, and the opening determines how carefully the rest gets read.

Weak Opening

CHIEFEVAL. Chief Petty Officer Harris is a dedicated and hardworking Machinist's Mate who consistently demonstrates technical excellence and strong leadership throughout the evaluation period.

Nothing here is verifiable. "Dedicated," "hardworking," and "consistently demonstrates" are filler that appears on most of the stack. The board learns nothing they couldn't have guessed from the grade.

Strong Opening

EARLY PROMOTE. MM1 Harris is my most technically versatile chief — sole E7 propulsion supervisor for a 6,200-ton DDG, owner of every engineering milestone on a 9-month deployment, and the architect of the CPO Mess's junior-enlisted mentorship program that produced the command's highest advancement cycle in a decade.

The strong version does four things in one sentence: establishes scope (sole E7, DDG, 9-month deployment), names a program she owns, connects her to the CPO Mess, and quantifies a CPO Mess outcome ("highest advancement cycle in a decade"). The board now knows what they're dealing with before reading a single bullet.

Performance Bullets

The ALL-CAPS headline is a short advertisement. The supporting sentences are the proof. Every bullet should stand on its own — if the headline disappeared, the sentences should still be specific enough to mean something.

Weak Bullet

ENGINEERING EXCELLENCE; MM1 Harris performed outstanding maintenance on propulsion systems throughout the deployment. She ensured the ship was always ready for operations and mentored junior Sailors to high standards.

There are no numbers, no specific events, no outcomes that can be verified or compared. "Always ready" and "high standards" tell a board member nothing they couldn't assume about any chief who deployed.

Strong Bullet

ZERO ENGINEERING CASUALTIES IN 14,000 STEAMING HOURS; MM1 Harris supervised all propulsion plant maintenance across a 271-day deployment — zero major casualties, zero unscheduled maintenance requiring port return. Identified and isolated an incipient main reduction gear bearing failure during routine monitoring; directed in-place repair that avoided a 22-day depot availability estimated at $1.4M. Engineering plant availability rate: 99.2%, highest in DESRON 15.

Scale (14,000 steaming hours, 271 days), critical action (bearing failure identification and in-place repair), cost avoidance ($1.4M), and a fleet comparison (highest in DESRON 15). A board member who has never met MM1 Harris now understands exactly what she prevented and how she ranks.

CPO Mess Bullet: Weak vs. Strong

Weak:

CPO MESS PARTICIPATION; MM1 Harris was an active member of the CPO Mess and played a role in mentoring junior Sailors and petty officers seeking advancement.

"Active member" and "played a role" are the polite way of saying the reporting senior ran out of things to say. This bullet burns a slot without making a case.

Strong:

REBUILT ADVANCEMENT PIPELINE FROM GROUND UP; Designed and led a 10-week CPO Mess advancement study program after command advancement rate fell to 18% — three sessions, 22 enrolled petty officers, 16 advanced on the spring cycle (73% vs. 34% Navy-wide average). Program adopted command-wide by CO direction; recognized as a DESRON 15 best practice by the fleet master chief during command assessment.

This bullet shows she identified a problem, built a solution, produced a measurable result, and had her work validated externally — three different levels of impact from one initiative.

Closing Statement

The closing is the reporting senior's bet. Selection boards want a direct signal: does the person who knows this chief best believe in her enough to stake their own record on it? Hedging language undercuts everything that came before.

Weak Closing

MM1 Harris has the potential to continue growing as a Chief Petty Officer and would benefit from the additional responsibilities and challenges that senior enlisted leadership brings.

"Has the potential" is the single worst phrase in a CHIEFEVAL closing. It signals doubt. A board reading this closing will not advance someone whose reporting senior sounds uncertain, no matter how strong the bullets were.

Strong Closing

MM1 Harris is a Chief in every dimension that matters — technical depth, CPO Mess ownership, and the uncommon instinct to fix problems before they brief. Advance to Senior Chief now. Select for NAVETS or Major Command SEA billet at first opportunity; she will raise the standard wherever she serves. Unreserved recommendation.

No hedging, no qualifiers. "Advance to Senior Chief now" is a direct instruction, not a suggestion. The forward look to specific opportunities signals long-term confidence. "Unreserved recommendation" closes the door on any interpretation that this is a conditional endorsement.

Five Mistakes That Kill Chief Selections

1. Writing E6 bullets with an E7 name. If every bullet is about personal technical execution and there's no CPO Mess, program-level, or command-impact language, the board reads a very good petty officer. Chiefs are evaluated as leaders of the Mess, not just workers in a shop.

2. Burying CPO Mess contributions in the closing. CPO Mess leadership belongs in the performance bullets as a standalone accomplishment with numbers. Mentioning it only in the closing reads as an afterthought.

3. Trait grades that contradict the narrative. If you're writing "best chief in the department" language but checking 3.0s on trait grades, the board notices. The narrative and the grades have to tell the same story.

4. Missing the stratification language. Phrases like "my #1 of," "best chief I've supervised in 18 years," "must advance," and "promote ahead of peers" are not hyperbole — they're signal. Boards use this language to rank-order candidates. Omitting it costs selection equity.

5. Soft quantification. "Supported 300 Sailors" is weaker than "sole HM1 for a 300-Sailor detachment, 218 consecutive days without relief." Same number. Three times the impact.

Put the Structure to Work

Getting the structure right is one problem. Getting the words out — especially when you're staring at a blank Block 41 with a deadline two days out — is another.

RapidEPR's Navy CHIEFEVAL generator lets you describe what your chief actually did and generates a draft block in the right format: ALL-CAPS headline cadence, scope language front and center, and prompts for the numbers that separate good bullets from board-ready ones. Iterate until it sounds like you wrote it.

If you're newer to the EVAL format in general, the post on writing strong military evaluation bullets covers the foundational structure used across all branches. And if you're struggling to find the numbers that make a bullet land, how to quantify accomplishments when you don't have hard numbers walks through six categories that surface metrics in almost any rate or job.

A competitive CHIEFEVAL is not about flattery. It's about specific, verifiable evidence arranged so a board member who has never met your chief walks away with no doubt about what they're advancing. The opening establishes credibility, the bullets prove it, and the closing bets on it. You have the structure now — go use it.
