OMAHA, Neb. (AP) — Superintendents in the Omaha area are studying the effectiveness of the Learning Community and have released a draft of their first joint report.

In 2007, the Legislature created the Learning Community, comprised of 11 school districts, to improve minority and low-income student achievement.

The report called “Learning Community: Time for Change?” says an open-enrollment student transfer system is more costly than before and hasn’t done much to improve socioeconomic diversity in schools. It also questions whether school districts alone can bring about the blending of poor and more affluent students.

But the report also shows strong support to expand early childhood education for students from low-income backgrounds.

The draft doesn’t include concrete recommendations, which officials say will be a part of the final report.
