Improving the academic performance of junior high school boys is key to reversing Wilkinsburg's "legacy of educational failure," said a certified public accountant who wants to open a single-gender charter school in the community. Andre Tucker, a Wilkinsburg native who graduated from Woodland Hills High School in 1997, presented the school board Tuesday with details of his fourth proposal in two years to establish a charter school. He said he would submit a formal 500-page application, which includes enrollment projections and information on funding, in time for the board's next meeting.
