This document discusses different ways to categorize tests, including by mode of response (oral, written, performance), ease of quantification of responses (objective vs. subjective), mode of administration (individual vs. group), test constructor (standardized vs. unstandardized), and mode of interpreting results (norm-referenced vs. criterion-referenced). Tests can be categorized based on whether responses are oral, written, or performance-based. Objective tests with quantifiable responses can be compared to yield scores, while subjective tests allow divergent answers like essays. Tests are also categorized by whether they are administered to individuals or groups, and whether they are standardized with established procedures or unstandardized for classroom use.
