In Rhode Island, teachers in a local public school have overcome animosity between their charter school counterparts, to joined together and dramatically raise reading scores for young children who choose their own books.

This rare teaching collaboration has introduced new strategies that have turned around some of the lowest reading scores in the state.

By the end of the first year of the program, the number of students in Kindergarten through second grade who were reading at grade level rose from 37 percent to 66 percent.

This year marks the 20th anniversary of the first charter schools, which were envisioned to be incubators for finding best practices that can be applied throughout public education.
