contributions to the fir&l mulctple variance differ from the apparant
atandard by rate and factor. @n the basis of pay grade medfans, differences
from the standard were etatistfcally significaut for all factor8
at pay gradeo E-4 and E-5 and not significant at pay grade E-6.
Pre-Testing for Controlled ~minations
The Navy’8 regular advancement examination is compoeed of 150
4 option, multiple choice questiors. In the construction of theae
instruments only 50% of the questions have item statistics and are
utilized to control the standard of the examination agalnat the deoired
criterion, The remainfw percentage of question8 are new and generally
cover the entire spectrum of difficulty. Closer adherrnce.to overall
a tandards can be acquired by simple pre-testing of the new questions
on selected populations. This in eesence will provide for a completely
controlled examination from the standpoint of item difficulty and discrimination.
Reliability Computer Check Study
i
7.
A detailed approach to one aspect of reliability checking for
computer operation8 ie given in another part of this surmary. The
paper wa8 presentad independently a8 prt of the Theoretical Seminar.
Four Cycle Bcaminin~ Periods
The regular advancement examfnattona are pr?marily discriminating
and administered Navy-Wide each February and August. The regular input
at pay grade E-4 cannot be maintained in 22 critical rates, vithout
disturbing the balance of the total system. The possibility of examining
these critical perrronnel duriw Hay and November with a qualifying type
oli examination ha8 been investigated and proposed a8 a poseible solution.
Simplified Tri-Serial Correlation
A byproduct of a latger project yielded a simplified triserial
correlation, result8 of which were presented at the national 1964 APA
conference. J88pCn’8 original formula for the triserial r ie rather
unwieldy and therefore has been passed by for 8Ome easier lees appropriate
correlstion technique. Jaspen’s formula equals:
‘tri p
ZaYa + (Zb - za) Y b - ZbYc
Za* + (Zb - Za)* +
