Why Are Charters Rated A-F or Not Rated?

By Ildi Laczko-Kerr

The 2017 A-F results provide accountability for a sizeable portion of public schools in the state; however, not all schools received a letter grade. The table below summarizes the percentage of schools that received a letter in 2017, by district and charter. Most of the schools classified as “not rated” are small schools, have their letter grades currently under review from the state, or identify as alternative or online, virtual schools. In 2017, 90 percent of all district schools received an A-F letter grade rating, compared to 65 percent of charter schools. That means 22 percent of charter students attended a school that didn’t receive a letter grade.

The following chart provides more detailed information about the “not rated” and “rated” schools in the state, by district and charter. For the 35 percent of the “not rated” charter schools, 19 percent are alternative schools, 12 percent are small schools and 3 percent are online schools. The State Board of Education is expected to develop separate accountability formulae for each of these types of schools in the future.
