PSY-335 Assessment and Testing covers the principles and methods behind psychological measurement, examining how testing instruments are designed, validated, and applied across clinical, educational, and organizational psychology contexts. The course builds a genuine measurement literacy that underlies credible psychological assessment practice.
Measurement as a genuine methodological discipline
The course treats psychological measurement as its own genuine methodological discipline — with real standards for validity and reliability — rather than assuming any test that produces a number is automatically a credible measurement tool.
Assessment applications spanning multiple psychology contexts
PSY-335 examines testing instruments across clinical, educational, and organizational contexts, reflecting that assessment competency genuinely transfers across these different applied psychology settings.

Frequently asked questions
Not every testing instrument that produces a numerical result genuinely measures what it claims to measure — a test can appear to work while actually being unreliable or invalid for its intended purpose — meaning credible psychological assessment requires rigorous evaluation of measurement quality, not blind trust in any tool that yields a score. PSY-335 treats measurement as its own discipline because sound assessment practice depends on genuinely understanding these validity and reliability standards, not assuming test results are automatically meaningful.
The core principles of sound psychological measurement — validity, reliability, appropriate test design — genuinely transfer across these different applied contexts, even though the specific instruments and applications differ, meaning a student who understands measurement principles broadly can apply that competency across multiple career paths. PSY-335 covers this range because assessment literacy is a genuinely transferable skill, not narrowly confined to just one applied psychology specialization.
