content specific prompts)
 Interviews(brief,private,10-minute
interview of each student)

10. CONSTRUCTION OF DIAGNOSTIC TEST
 Identification of the problem areas
 Detailed content analysis
 Listing all the learning points in the logical
sequences
 Writing test items for each learning point
 Clubbing the items around the learning
points

11.  Providing clear instructions
 Preparing a scoring key and a
marking key
 Providing the time limit as
required by individual students
 Administration of the test

12. PREPARING THE SCORING KEY AND
MARKING SCHEME

objective type questions and marking
schemes made for the essay and short
answers.

Analysis of a
learner’s performance in writing
and speaking in terms of
grammatical accuracy or linguistic
appropriacy.

17. DISADVANTAGE
Difficulty in
identifying whether a learner
masters the present perfect/past
tense distinction.

A useful test not only provides
information about students
achievement but also reveals the
instructional effectiveness as well. If
we examine individual performance,
we should able to determine each
student degree of proficiency on each
objective.
