Perhaps there could be short assessments to verify basic objective mastery around a particular concept followed by rich capstone-like projects that could measure several competencies and be reviewed on an on-demand basis by an outside party, similar in some respects to how Western Governors University manages its assessments, for example (and yes, Western Governors’ assessments are designed by psychometricians).
The assessments could also presumably be more bite-sized and not interrupt learning in school for several days."...
