Publish the concordance formula, not just the table
The advice. Districts and schools would want to see the formula used to produce the concordance, not only the resulting lookup table.
Why. A lookup table is opaque. A district that cannot see how a Smarter Balanced score becomes an M-STEP score cannot judge how much to trust any single cell, cannot explain the mapping to a parent, and cannot detect when it is being applied outside its intended range. Publishing the method converts the table from something to be believed into something that can be checked.
Status. Open. No record of OEAA committing to publish the derivation.
