Blueprint Test matrix Is it necessary?
Blueprint Table of specification. Establish the length of each test and the number of test items measuring each objective It ensures content validity. It provides consistency from a test to the next. Ensures a balanced test. Reflects an appropriate distribution of the course subjects across course objectives.
Blueprint / Table of specification A table which relates learning outcomes to content Indicates the relative weight to be given of the various areas of the course content
Why a blueprint? To provide assurance that the test will measure a representative sample of the learning outcomes and the subject-matter content to be measured in a balanced manner.
How to prepare it? Identify the learning outcomes and content areas to be measured by the test. Weight the learning outcomes and content areas in terms of their relative importance. Build the table in accordance with these relative weights by distributing the test items proportionately among the relevant cells of the table.
Blueprints Objectives to test items Content versus Level Content Versus Content See attached Doc.
