About 120,000 students in Maryland are taking the state's newest standardized tests this month, and by most accounts the process has gone well. After two years in which the state's assessments were tied to a curriculum that is no longer being used, the tests and what's being taught in the classroom are finally aligned. That's why we're puzzled by Gov. Larry Hogan's recent suggestion that he might want to revisit whether the state should be using the tests to gauge student progress, reiterating his campaign line about hitting the "pause button" on the test. The new assessment has barely been tried, and scrapping it now not only would be costly for the state but would waste years of effort educators spent developing it. Unless some serious, unanticipated flaw comes to light as a result of this year's test, it's far too soon for talk about replacing it with something else.
