A new report issued by Bridge Magazine this week shows 52 Michigan public school districts and charter schools were named Academic State Champions for the 2011-12 school year.
Districts were ranked based on schools' test scores adjusted for family income, showing where students are not only achieving but overachieving.
According to the analysis, a Value-Added Matrix (VAM) score of 100 indicates students are achieving at expected levels for their income level. The higher a school's score, the better their students are performing on standardized tests.
Trenton Public Schools were ranked 424th overall out of 560 school districts and Grosse Ile Township Schools were ranked 357th.
TPS received a VAM of 95.92 and GITS received a VMA of 98.07.
Trenton Superintendent Rod Wakeham said the report is a new indicator for school districts to use.
"Added years of data will determine how useful it can be for schools to use as an improvement tool," Wakeham said
