Validity and technical documentation

One page per product, written so an outside reviewer can check it. Each page says what we measured, what we have not measured yet, and which version of the code and data it describes.

• DecipherU Match technical manual: purpose, items, scoring weights, data sources, samples, reliability and validity evidence (none yet), fairness checks, limits and version history.
• How practice questions are made and checked: drafting, source checks, the second review, the weekly re-check, with counts read from the question banks.
