Teacher-made tests are intended to measure the specific learning outcomes of a particular teacher's students and are not scientifically prepared, while standardized tests aim to measure general educational outcomes across multiple schools. Standardized tests involve preparing a design, pilot testing items, analyzing items to discard unsuitable ones, final testing a sample population, establishing scoring procedures and norms, and determining validity and reliability, while providing guidance for teachers but potentially making inaccurate judgments of students.

3. A teacher made test is
intended to measure the
outcomes of learning which a
particular has in mind.

4. •Guidance for teachers
•Teacher can measure his
own students learning
outcomes

5. • Teacher made test are not
scientifically prepared.
• Specific set of students can handled
by the teacher
• The type of behavior changes
covered are often limited scope
• The items of teacher made tests are
seldom analysed and edited.

6. The standardized test is
intends to measure the
educational outcomes
aimed at generally by a
number of schools.

7. STEPS IN CONSTRUCTION OF A STANDARDIZED
TEST
• Preparation of a design and blue print
• Preparation and administration of a pilot- test or preliminary
test
• Item- analysis by which unsuitable items are discarded from
the test
• Preparation of final test

8. • Selection of sample for the final test
• Administration of the final test to sample
population
• Preparation of a scheme of evaluation-scoring
key and marking scheme
• Scoring of the answer script

9. • Establishment of norms
• Determination of validity and reliability
• Preparation of manual book let or test manual
• Containing the scope of the test and
instructions for administration, meant for
general use

10. Advantages of standardized test
• Guidance for teachers
• Sets an understood standard
• It is totally unbiased
• Results are quantifiable
• A standardized test is very practical

11. DISADVANTAGES OF
STANDARIZED TEST
• An inaccurate judgment
• Questions are general in nature
• Scores are influenced by external factors like
fatigue
• Result does not allow educators to update
their instruction method
