(1) Phase Aggregate Score (PAS). An NFS’s PAS is a
comparative ranking based on the previous population of
completers for a specific phase or portion of a phase of
aviation training. PAS indicates only NFS performance relative
to a normative population of other recent NFSs. Under the MNTS
system, PAS is not by itself an indication of whether an NFS has
met the criteria necessary for winging or continuation in
aviation training. PAS is calculated for each block within a
curriculum, for the subset of blocks completed by an NFS still
in training (Interim PAS), and for the entire phase.
MNTS SNFO Calculations. From a population of previous
SNFOs, an SNFO’s PAS is calculated using equation (1), below:

S – SNFO Score
NMU – SNFO NMU
Acad – SNFO Academic Grades
M1 – Squadron Average Score
M2 – Squadron Average Number of Marginals and Unsats
M3 – Squadron Average Academic Grades
S1 – Standard Deviation of Squadron Score
S2 – Standard Deviation of Squadron NMU
S3 – Standard Deviation of Squadron Academic Grades
(2) NSS. NSS is calculated to correct for potential
non-normality in the distribution of PAS. NSS is calculated for
each block within a curriculum, for the subset of blocks
completed by an NFS still in training (Interim NSS), and for the
entire phase. NSS is calculated from PAS by using equation (2),
below:
