This past summer, days before the academic year started, about 700 teachers and more than 13,000 students in Rosemount got an early start on school.
The teachers spent two 12-hour workdays assessing elementary students, courtesy of a change in the school calendar approved in the spring that ends the school year earlier but uses those saved days for periodic student assessment.
Theoretically, teachers will have a better sense of their students' literacy and thus tailor lessons sooner than normal. And by making the classroom teaching more focused and more efficient, academic performance is expected to improve, district officials say.
"This is a huge change," said Steve Troen, the district's director of teaching and learning, "Our district really has been looking at using data to drive our instruction."
The youngest students were assessed during the summer on such things as how well they identified letters, what if anything they comprehended about reading, even how they held a book that was given to them.
Rosemount is one of only a few districts conducting early assessments, but educators said the district is the largest and probably has the most extensive assessment program.
Another change to the school calendar, for example, will allow secondary teachers to take a day every few months to conduct data analysis of their students and tweak the curriculum, focusing on students who are behind or not meeting expectations.
"I don't think another district did it the way we did it," said Jim Smola, president of Dakota County United Educators, the union representing the district's 2,000 teachers. "It was a vast undertaking."
