Amends existing law to revise provisions regarding mastery-based education.

This legislation will allow more public school districts and public charter schools to participate in Idaho's mastery education initiative by removing the existing statutory cap on participation. The cap was put into place as the mastery initiative began, in order to create an incubator cohort of schools. As Idaho has made progress, more schools wish to participate. The legislation also adjusts the statute to support Idaho's long-term transition to mastery education.
