"It's still a pretty wide gap," said Tom LaBounty, the district's coordinator of research and testing.
"It's a pretty drastic change," LaBounty
"And it's interesting that the year before that, we had such an increase."
Changes in evaluation
said the release of the Minnesota Comprehensive Assessment represents the "first glimpse" of an evolving picture of how schools are doing.
Previously, before the state was granted a waiver by the feds, MCA test results were used to identify under-performing schools, which by 2014, were supposed to be 100 percent proficient in math and reading.
Minnesota's new homegrown system takes into account not only proficiency, but also academic growth over time and progress in closing the achievement gap - all of which goes into calculating a school's multiple measurement rating, or MMR.
Those findings are expected later this month.
"I think the results (released today) offer a limited view of how our schools are performing," LaBounty
