All 20 of Rochester Community Schools elementary, middle and high schools were among the top 35 percent of schools statewide in a "Top-to-Bottom" ranking of public schools released today.
Three elementary schools — Brewster, Musson and North Hill — ranked in the top 25, and several others ranked close behind.
The Michigan Department of Education is required each year to produce a list of persistently lowest achieving schools; last year, the department also published an overall Top-to-Bottom ranking of all schools in the state.
None of the Rochester schools were among those labeled as "persistently lowest achieving."
The Top-to-Bottom ranking includes all public schools and is based on student proficiency and improvement in math, reading, writing, science and social studies, as well as graduation rate and achievement gaps between students within a school.
The department acknowledges the methodology used to rank the schools is complex, but says it is a true apples-to-apples comparison of schools, according to an explanation of the methodology posted on the department's website.
Here's how the individual Rochester schools ranked; a percentile rank of 99, for example, means that 99% of schools statewide scored below that school's result.
