bullseye views od validity and reliability

T.J. Elliott’s decidedly non-expert blog on tests, assessments, exams, quizzes, assessments & claims that shape our lives

Testing: A Personal History

A highly idiosyncratic account of life as a series of tests exploring both their influence and infamy as instruments “by which the existence, quality, or genuineness of anything is or may be determined” — as Dr. Johnson described them. This blog contains the reflections and unresolved questions of a generalist still trying to understand how these mechanisms became so unpopular and what the world might do differently in educational and other types of personal measurement.

Glad to have others join the conversation.

But it’s not an argument.
