Okay, here's the quick and dirty on FITREPs...
- No 1 of 1 EP? No breakout EP? highwater trait average <= RSCA? You are almost certainly now non-due-course.
- You may have to ask your CO their RSCA. They don't have to give it to you.
- Block 41 needs to recommend you for CO or Flag early and often; otherwise is a negative signal.
- Block 42 first and last line are a little important. The middle truly does not matter.
With this knowledge you should take action by:
- If not given, ask for CO's RSCA every time you debrief a FITREP.
- Put "Flag Officer" and "CO Afloat" in Block 41 starting with your first observable FITREP.
There's other stylistic things - document your performance with hard metrics, etc. - but that's covered a lot. The other stuff above isn't really covered much.
I disagree with the bullet points noted above. Recommending a JO for CO at sea and flag officer in block 41 tells the board (particularly statutory) that you don't know how to write fitreps more than it says anything about the JO's performance, and could lead people to say "so is this JO actually recommended for DH/O-4 or not? Was that flag officer recommendation a joke from the JO that made it through chop?" The 'normal' custom is 1 operational billet up for block 41 and 2 up for the secondary recommendation for a top performer and/or transfer.
I also somewhat disagree with block 42 body not mattering. Phrases that indicate breakout performance consistent with the precepts get circled and briefed. Additionally, the recommendation in block 41 should also be repeated in block 42 (again, leave no ambiguity).
Finally, the CO's RSCA is easily viewed by looking at your ODC/OSR on the bupers website; no need to ask about it.
From a practical perspective, a JO isn't going to be able to control his grade or the recommendations given in block 41 or 42. He can check for administrative errors (continuity, recommendation in block 41 also appearing in block 42). Other than that, it's about understanding what's considered important for top performance and then doing those things, and that comes with understanding that the parts of the job you like doing or do well aren't necessarily the parts of the job your boss or community finds most valuable.
What I would encourage JOs to do is understand what 'best and fully qualified' actually means for the sailors in their divisions so that the eval reflects those qualifications and the writeup provides OQE that they perform those duties well. If you want to talk about a group of people who on the whole woefully falls short of understanding how to write in fitrep/eval-ese, it's senior enlisted sailors.
