PENYETARAAN TES UAN: MENGAPA DAN BAGAIMANA?

Abstract

Debates concerning
what is right and what is wrOng with national final
examination (UAN) in Indonesia
are not new. National Final Examination (UAN),
a significant process
using a test form to measure learning output, has been
developed to provide useful information for the decision makers (parents,
educators,
policy"makers and the local community). Multiple forms of a
certification
exam are desirable for a variety of reasons. However, the problem of
comparability
among test scores using different test forms must be addressed in
order to insure fairness and consistency in each testing situation. Test forms must
be interchangeable across test administrations. Psychometric procedures known as
equating
methods can be utiliz~d to produce comparable (equated) scores.
Equating procedures consist of
(1) a design for collecting test data for equating, (2)
a clearly defined level of expected correspondence among test scores, and (3)
specific statistical procedures that are
used to estimate score correspondence. The
process of
equating is used to obtain comparable scores when more than .one test
forms are
used in a test administration. In many situations in test administration,
more
than one form of the tests are used for security reasons. Beside, by test
equating, a test form can be administered more flexible in the context of
environment
and time. There are several techniques and methodologies that can he used
in equating test fonns. Generally speaking, these techniques and methodologies can he
divided into three major activities, namely determining test equating desigu, determining
the test equating methods, and determining the way
of test equating will be taken. The
magnitude of standard error of estimate (SEE) is used to evaluate which is the most
accurate
method of test equating. The less the score of standard error of estimate
the more accurate
of the test equating method
