The Greater Raleigh Chamber of Commerce and the Wake Education Partnership will release Friday the new student assignment model developed by education consultant Michael Alves.

Alves was hired by business leaders to develop an assignment model that factors in student achievement along with stability, family choice and proximity. The Wake County school board has not decided whether it will use the Alves plan, which some critics argue is an attempt to revive the old diversity policy.

Under Alves' controlled-choice plan, parents would rank which schools they'd want their children to attend. School staff would use various factors for determining which choice to give to students.

School staff are working on a plan starting for the 2012-13 school year that would implement on a wider basis the new policy that stresses sending students to neighborhood schools.

The event will take place at 10 a.m. at the Embassy Suites, 201 North Harrison Blvd. in Cary.The event will take place at 10 a.m. at the Embassy Suites, 201 North Harrison Blvd. in Cary.
