Introduction

We have already discussed the Construction of an achievement test used in school-based
assessments and also in external examinations. Different steps like designing, blueprinting,
construction of questions, formating the test and moderation of the question paper were described
for developing good question papers. When we talk of standardisation of an achievement test, it
is the process of desiring comparative norms that distinguishes the formal standardised test
from the informal objective test of achievement. But any programme of standardisation demands
additional requirements like :
(i) more critical analysis of subject-matter;
(ii) more careful formulation of test material;
(iii) more exacting refinement of test items;
