In the January 10th editorial “Focus on Instructional Time, Not School Days,” we asserted that over six years ("say from 1st to 7th grade"), students in Houston Independent School District spend a full year more in school than their peers in Cleveland. That span of time (from 1st to 7th grade) is actually seven years and the resulting difference in school time is about 77 days (using Cleveland’s school day)--not a full year. As Gadfly goes in search of a new abacus, you can find more commentary on the school day/time debate here.
