D. Application of tha Achievamant Indax. I would like to turn now
to 8 study on an application of the � chievanont ladax in a training situation.
A8 we Indicated, the � chievmnant index can most easily ba darlvad for
individuala by men8 �� � ratio of. actual divided by predicted achievomeat.
1. A Note on Under sod Ovarachiavcmunt. F’rochlich, A. P. and
ttayo, C. D. Par8unr;el end Gu:ldanca Journal, Merch 1963.
This ~jzxnel rrticle rcp:rorantr a susxmary of the raraarch on the’
� chiovammt Index and ohoutd be � ppropos al80 to the termination of my
own remarks on thin subject. Froahllch indicates two applicctionr of
the � chiavamant index (a) Bareuch md (b) Prediction. We have dwelt
at langth on the potrntlal thlr Index haa for purpoaar of baric rsrearch
on learning gala and motiuatImon depandtng on the nature of tha variable(s)
partialad out; i.a., whathar ,achiavmant or aptitude 18 ra8lduallrad. As
regards It8 predictive aspacts, we elro heva indicated that the achlevaindex
doe8 pradlct training criteria but doar not add to the training
grade. Ae notad, it repromate the unpredicted variance of a training
grade which, whan corabinad with the predicted variance of that grade
sat8 the multiple I%” a8 quel to the rtmple “r” (by urlng the trslning
grade alone) In predicting en external criterion. Proehlich cleerly
point8 that fact out, but emphasized that the marit of this dichotomy
liar in It8 iroletlon of variance vhich wa8 not predicted by the ability
maa8urtr utilized. Thu8, .when derived aarly in training, tho � chlevantmt
indax 18 conridarad to hava marit In counseling “low-achiaver8” (i.e.,
those who scored 1.00). Iha study indicated that, “if tha unpredicted
pert of academic achiewment measurer tnotlvationel varience, it might be
bvpotherieed thet if underachla~var8 of various ability levelc could be
motivated to put out more effort,
heve more interest, or t8ke on more
positive attitude8 toward their studfe8, Sane might im;*‘ovc their final
gradas .‘I
In resume, it can be reid thet the achiavemant Index hao 8 graat
potential for basic research in tha difficult area mearurlng non-aptitude
variance ruch a8 motivetion. The pertiel end part corrclatlonr offer a
good technique to isolate andi identify the corralatom of this rariduel.
SOW use of this Indax in tha form of a ratio ha8 been made in uavol air
technical tralnfng for counsalinng purpor*r. It is conrldarad that further
research Into the netura of the � chlavrsnent index will prove to
extend It8 role in an applied sannre.
II Prediction of School Achievamant
The recond approach to job proficiency maarurar i8 the pradiction
of school achlevamant. This anployed the cl~s8lcrl regrarrion
end pens/fail frequency proctcdurar to derive prediction8 and sppronimate
odd8 to succeed various ochools in the Naval Air Technical Training
Comand. The vrriebler utll:itad arc the � veilebla relaction end treinlng
grede8. The technical School8 involved were the machaolcal and avionic8
ratings. Briefly, I would like to prarrst an axample of the correlational
teblt8 end al80 the parr/fail frequency teblas and their role in tha
quality control of traiatar.
