What Will I Learn?

The Validity Course gives you a focused, practical toolkit for building and evaluating high‑quality measures. Learn to define constructs clearly, design items with strong content coverage, run factor analysis and IRT, assess criterion relationships, and address threats such as bias and administration issues, then synthesize evidence into clear decision rules and implementation guidance for real‑world use.

  • Run psychometric analyses: EFA, CFA, IRT, reliability, and DIF checks fast.
  • Evaluate criterion validity: correlations, regression, and incremental validity.
  • Create a full validity argument: synthesize evidence, set cutoffs, and report.

Your classes are perfect. I purchased the one-year package and finally have the chance to follow several topics I'm interested in without having to switch platforms... thank you for everything you do, I've already recommended you to others...

I like how the lessons get straight to the point and how I can switch chapters and skip content I don't need.
