Block 43 is the most valuable real estate in your entire Navy career, and most Sailors waste it. It is the comments and performance section of the eval, the space where your rater makes the case that you outrank your peers. A ranking board reads it in seconds. A strong Block 43 survives that read. A vague one sinks a good Sailor.
This is how Block 43 is structured, the writing formula that makes a bullet land, and the exact power verbs and metrics that separate a promotable eval from filler.
Block 43 is the narrative comments section of the Navy evaluation, where the reporting senior justifies the Sailor’s ranking and promotion recommendation through bulletized accomplishments. Strong Block 43 bullets follow a fixed skeleton, action verb, scope, quantified result, and outcome, and lead with the biggest impact first because a ranking board may never reach the last line.
What is Block 43 and why does it decide your eval?
Block 43 is where the eval stops being a form and starts being an argument. The trait grades give a number. Block 43 gives the evidence, and it is the part a selection board and a ranking board actually read to decide who advances.
Here is the fleet truth that never changes: the exam gets you to E-6, but your evals get you to E-7. By the time a chief board convenes, your last five years of Block 43 comments are your entire package. Every bullet you earn today is a line a board reads years from now, which is why the brag sheet habit matters at every paygrade.
What is the formula for a strong Block 43 bullet?
Every board-ready bullet has four parts in a fixed order:
- Action verb. A strong past-tense verb that shows you drove the result. Led, directed, engineered, overhauled, mentored.
- Scope. How big was it? Sailors supervised, dollars managed, systems owned, watch stations covered.
- Quantified result. The number that proves impact. Percentages, dollars, hours saved, inspection scores, days ahead of schedule.
- Outcome. What it produced for the command. The mission effect the board can weigh.
Put together, it reads like this: “Led 12 Sailors through a $2.4M maintenance availability completed three weeks early, directly enabling the ship’s on-time deployment.” That single line survives a ninety-second record review. Compare it to “Outstanding leader, always gives 100 percent,” which could describe anyone and proves nothing.
The test is simple. If you can swap any other Sailor’s name into your bullet and it still reads true, the bullet is too vague. Rewrite it until it could only describe you.
Which power verbs actually work in Block 43?
Boards read thousands of evals, and weak verbs blur together. Lead each bullet with a verb that shows ownership and force. Strong options by category:
- Leadership: led, directed, supervised, mentored, spearheaded, championed
- Technical: engineered, overhauled, troubleshot, restored, modernized, qualified
- Process and program: managed, streamlined, standardized, coordinated, executed
- Impact: delivered, drove, achieved, produced, recovered, eliminated
Avoid the verbs that signal participation instead of ownership: helped, assisted, participated, supported, was responsible for. They tell a board you were near the work, not that you owned it.
How do you use metrics to prove impact?
A number turns a claim into evidence. Every bullet should carry at least one, and the strongest bullets carry a number tied to a command-level outcome. The metric categories boards trust:
- People: Sailors led, trained, or qualified, and how far ahead of the standard.
- Money: budget or equipment value managed, cost avoided, savings produced.
- Time: days ahead of schedule, hours saved, response time under a casualty.
- Quality: inspection scores, zero-discrepancy results, error rates driven down.
- Volume: maintenance actions completed, watches stood, evolutions supported.
When you do not have a hard number, use a comparative anchor instead: “highest of 12 work centers,” “double the division average,” “first perfect score in six assessments.” Relative scale still proves you outperformed, and boards rank on comparison.
How should you order and open Block 43?
Rank your bullets strongest first, because the reader may never reach the bottom. The opening statement, the first line of Block 43, should stake your ranking claim in one sentence: superlative or ranking, plus scope, plus your defining result. Everything after it is evidence that backs the claim.
The rest of the block should read as a descending list of proof, each bullet self-contained, each carrying its verb, scope, number, and outcome. Close with a promotion recommendation the board can quote directly: clear, specific, and unhedged.
Build every bullet from your running brag sheet, not from memory the night before inputs are due. The Sailors with the strongest Block 43 are the ones who documented the win the week it happened, then translated it into the four-part skeleton at eval time.

FAQ
What is Block 43 on a Navy eval?
Block 43 is the comments and performance narrative section of the Navy evaluation, where the reporting senior justifies the Sailor’s ranking and promotion recommendation through bulletized accomplishments. It is the part ranking boards and selection boards read most closely.
How do you write a good Block 43 bullet?
Use the four-part skeleton: a strong action verb, the scope of responsibility, a quantified result, and the command-level outcome. Lead with your biggest impact, and make sure the bullet is specific enough that no other Sailor’s name could replace yours.
What words should you avoid in a Navy eval?
Avoid participation verbs like helped, assisted, participated, and supported, and empty phrases like hard worker, team player, and gives 110 percent. They signal you were near the work rather than owning it, and they carry no evidence for a board.
How many bullets should Block 43 have?
There is no fixed number, but every bullet should earn its space with a verb, scope, number, and outcome, and they should be ranked strongest first. Quality and order matter more than quantity, since a board may not read past the first few lines.
