This document discusses norm-referenced tests (NRTs) and criterion-referenced tests (CRTs). NRTs indicate how a pupil's performance compares to other pupils, while CRTs indicate how a pupil's performance compares to an established standard or criterion of mastery. There are key differences in how NRTs and CRTs are constructed and evaluated. The document also discusses the importance of instructional objectives in guiding teaching and developing valid tests to measure student attainment of objectives. Objectives help translate broad societal goals into specific classroom instruction and assessments.

NORM-REFERENCED AND CRITERION- REFERENCED TESTS
Norm-Referenced Test (NRT) indicates how a pupil’s performance
compares to that of other pupils.
Criterion-Referenced Test (CRT) indicates how a pupil’s
performance
compares to an established standard or criterion thought to
indicate mastery of a skill.

COMPARING NRT AND CRT
Criterion- Referenced Test must be very specific if they are to
yield information about individual skills.
The Norm-Referenced Test ,in contrast, tends to be general.
In the CRT, 80% of the students completing a unit of instruction
are expected to answer each item correctly, while in an NRT, 50%
are expected to do so.
Note: Table 4.1 illustrates differences between NRT an d
CRTs.

NRT and CRT and Linguistic, Cultural, and Contextual
Sensitivity
NRTs compares a students performance to a norm table based
on nationally representative sample called a norm group or
Normative sample of students in the same grade and of a similar
age.
CRTs do not utilize comparisons to norm groups to obtain scores,
differences between a pupil’s background and that of the students
in the norm group are not relevant. Use of CRTs with pupil’s
from diverse backgrounds may be more appropriate—but only
if a CRT is appropriate for the purpose of testing.

Norm and Criterion- Referenced Test and Validity Evidence
>Teachers should have some objectives in mind when
they teach.
Short-term and Long-term objectives
Examples:
Short-term-The learners will count numbers 1-10.
Long-term- The learners will master all phases of
addition.

WHY OBJECTIVES? WHY NOT JUST WRITE TEST ITEMS?
Instructional activities tend to vary across educational
Institutions, and they range from flexible to rigid. These
Instructional activities tend to be determined by
Instructional objectives which tend to be derived from
Educational goals and state academic standards which
Tend to reflect societal attitude and values.

KINDS OF GOALS AND OBJECTIVES
1. Behavioral Objective (specific)- it specifies an observable
measureable behavior to be exhibited, the conditions under
which it is to be exhibited, and the criterion for mastery.
2. Expressive Objective (general)- it specifies an educational
activity but does not specify the particular outcome of the
activity.

HOW CAN INSTRUCTIONAL OBJECTIVE MAKE A TEACHER’S
JOB EASIER?
Instructional objectives help the teacher clarify and organize
Instruction, enabling the teacher to save time in the long run.
