When the school year started, 103 children were enrolled in the Ewing Marion Kauffman Foundation’s attempt to run its own charter school — an endeavor being watched nationally as the well-known research foundation becomes the practitioner.
More than nine months later, as the inaugural class’s fifth-grade year finally ends this week, 91 are still on board.
Between the longer year and the longer days, they’ve spent 35 percent more time in school than students on a regular school calendar.They’ve endured daily double doses of math and reading and extra tutoring.
In return, Principal Hannah Lofthus said, the students on average have gained 2.4 grade levels in math, 2.1 grade levels in reading and 2.3 grade levels in science.
