The Michigan Department of Education released color-coded school and school district ratings Tuesday.
The new rating system, called School Accountability Scorecards, assigns each school and district a color based on a combination of student assessments, graduation rates, attendance rates and other factors.
Schools across Northville received a "Yellow" rating. Northville High School was one of those, which means it earned between 60 percent and 70 percent of possible points based on certain assessments.
The Northville Public Schools district detailed what it plans to focus on to increase achievement based on the ratings. See the chart above.
However, Northville High School ranked in the 94th percentile statewide. Rankings compare public schools to every other public school in the state according to a percentile. That means Northville High School has out-scored 94% of the schools across the state.
Each of the K-12 Northville schools achieved a percentile ranking above the 90th percentile of schools, according to the district's annual report. The ranking is based on student achievement, academic growth of all students and the gap between the highest and lowest scoring students in the school, the report said.
Why did Northville schools score lower?
According to Chris Janzer, an assessment specialist at the Michigan Department of Education, some schools received lower ratings in subgroup areas, which brought the overall rating down.
Cooke School, a special education center, received a "Red" rating as a result of having 93 percent of students participate in the state assessment program instead of the 95 percent target, according to Northville schools education report.
You can find more information about audit checks in a page from the department of education's guide to scorecards. It details how different scorecard components can affect a school's overall rating.
Overall achievement targets were met across all students, and in most subgroup calculations, the district's report said.
