Pittsburgh Public Schools Superintendent Mark Roosevelt tonight announced a change of plans for the district's high schools, saying he wants to keep Pittsburgh Schenley High School open until all of its current students have graduated.

He made the announcement at a school board meeting 24 hours after about 250 people, including dozens of students, rallied outside school district offices to demand the school remain open.

Mr. Roosevelt said he wants to move the school, intact, to the former Reizenstein Middle School building in Shadyside in the fall. He would close Schenley once all current Schenley students have graduated. Schenley won't accept any fresmen next school year; those students would be assigned to other schools.

Mr. Roosevelt said the Schenley building in Oakland must be closed because of maintenance problems. Last month, he proposed reassigning students to three other buildings as part of a broader plan for improving district high schools.
