11. TABLE OF SPECIFICATIONS
The purpose of a Table of Specifications is to identify the
achievement domains being measured and to ensure that a
fair and representative sample of questions appear on the
test. Teachers cannot measure every topic or objective and cannot
ask every question they might wish to ask.

A table of specifications (TOS) can be used to help teachers
frame the decision making process of test construction and
improve the validity of teachers' evaluations based on tests
constructed for classroom use. In this article we explain the
purpose of a TOS and how to use it to help construct classroom tests.

12. 1. What are the components of the TOS?
2. How do you calculate the number of items
in TOS?
(number of days/total number of days)
x total number of items

14. What are different formats of a test table of
specification?
There are three (3) different types of TOS:
– A one-way TOS maps out the content of
topic, test objectives, number of hour spent, and format,
number, and placement of items.
– A two-way TOS reflect not only the
content, time spent, and number of items.
– this type of TOS reflects the features of
one-way and two-way TOS. One advantage of this format is
that it challenges the test writer to classify objectives based
on the theory behind the assessment.
