1. For a TOS to ensure test content validity, what parts must it have?
Considering Parts of a TOS to Ensure Test Content Validity
These parts of the Table of Specification ensures content validity of a test:
- topic
- number of items
- number of hours
Topic
When talking about content validity, the topic or the content is on top of the consideration. For a test question to have content validity, the topics included in the test during construction should have been discussed or was discussed during the covered time frame that was identified beforehand.
Number of items
The number of items to be given in each discussed topic or content should be taken into consideration also to ensure test content validity. The number of items per topic is very important since it tells how many items or questions each topic should have base on the number of hours spent in discussing the particular topic. Say for example, a 2 hour class discussion about adjectives must have more items in the test compared to the 1 hour discussion about nouns.
Number of Hours
Last but not the least, the number of hours is important also for a test to have content validity. The number of hours spent in discussion of a particular topic or content simply determines the weight in terms of items or questions to be included under each topic or content.
