Like the Cleveland Browns on a Sunday afternoon, the Ohio General Assembly is fumbling about with the state’s value-added system. One month ago, I described two bizarre provisions related to value-added (VAM) that the House tucked into the state’s mid-biennium budget bill (House Bill 487). The Senate has since struck down one of the House’s bad provisions—and kudos for that—but, regrettably, has blundered on the second one.
To recap briefly, the House proposals would have (1) excluded certain students from schools’ value-added computations and (2) changed the computation of value-added estimates—the state’s measure of a school’s impact on student growth—from a three-year to a one-year calculation.
I argued then that the House’s student-exclusion provision would water-down accountability, and that reverting to the one-year estimates would increase the uncertainty around schools’ value-added results.
The Senate has struck down the House’s exclusion provision. Good. But it has failed to rectify the matter of the one-versus-three-year computation. In fact, it has made things worse.
Here’s the Senate’s amendment:
In determining the value-added progress dimension score, the department shall use either up to three years of value-added data as available or value-added data from the most recent school year available, whichever results in a higher score for the district or building.
Now, under the Senate proposal, schools would receive a rating based on whichever VAM estimate is higher—either the one-year or the three-year computation. (Naturally, schools that just recently opened would not have three years of data; hence, the “as available” and “up to” clauses.)
