Can you explain how far cadets typically move within the OML between their position before LDAC, and their position after?
Reason I ask, is that it looks like LDAC (without counting the APFT portion of LDAC) composes about 22.5% of the OMS. Counting LDAC + LDAC APFT, LDAC is about 32% of a cadet's total OMS. I think it is reasonable to count the APFT given at LDAC as part of LDAC b/c what if a cadet is feeling physcially subpar at LDAC and his/her APFT from school is 280, but at LDAC is 250), it can change the OMS substantially.
LDAC scores can get a bit confusing.
There is the Overall E, S or N, but there are also dimensional scores, 17 I believe. There are 6 categories, if a cadet gets an E in 3 and an S in three then they need to have at least 9 dimensional E's to get an overall E.
The LDAC score is not simply whether the cadet gets an overall E or S, it also has to do with how many dimensional E's they get. If a cadet gets an overall S but their score was 6 E's and 6 S's with 8 dimentional E's they can still get a fairly good point total for LDAC.
As far as the APFT there isn't much they can do if they have a bad LDAC APFT, tha's why it's so important to have good scores your junior year. My son was one of those that had 325 plus APFT scores on both graded tests his junior year and got a 287 at LDAC. They didn't count 20 plus PU's, the guy next to him didn't have one that didn't count, it was pretty arbitrary grading. I think now that the NCO's are grading the APFT you will start to see more balanced grading. I'm sure the APFT score at LDAC hurt him a little, it kept him from getting Recondo which would have added an extra .5 to his OMS, it was just something a lot of cadets had to deal with.
As far as how much the cadets move on the OMS score after LDAC you would have to look at the final OMS eval for each cadet. It is hard to determine the difference because of the dimensional scoring how they figure those into the overall LDAC score.
I can give you one example:
My son had a 3.5 GPA, received an overall E at LDAC with 3 E's and 3 S's and 12 Dimensional E's, he was ranked #2 on the battalion OML and attended Airborne and took one semester of critical language. He finished at 6.43% on the National OML.
A fellow cadet at his school had a higher GPA, 3.7 I believe, he received an overall S at LDAC with 6 S's and 5 dimensional E's, he was ranked #1 on the battalion OML, did not go to Airborne or any summer training, and took one semester of critical language. He finished 21.9% on the National OML.
So from that you can see that LDAC can have a real impact on the OMS score.
