The D.C. school board last night named a principal for Spingarn High School. The school has been without a permanent principal since July 1977.

Clemmie Strayhorn, currently assistant principal at Douglass Junior High School, was named to the post at the high school at 24th Street and Benning Road NE.

He was named as a "permanent probationary principal," which carries a two-year appointment to the principal of the school within that time, he becomes an acting principal and the position becomes open to other applicants.

The baord met in a special closed session before last night's regularly scheduled meeting to discuss was filed this week against the baord of education, school Superintendent Vincent Reed and two other school system officials by a former assistant principal at Spingarn.

The former assistant principal, Arthur E. Jenkins, alleged that the board, Reed, and the school officials had discriminated against him in his attempts to become principal of the school. The suit was filed Tuesday in D.C. Superior Court.

School board president Conrad Smith said the board decided to hold the special meeting on the Spingarn principalship because of concern voiced by parents at the school that classroom instruction at Spingarn was suffering because there was no permanent principal.

Betty Anne Kane formally submitted here resignation as a member of the board. Kane will become an at-large City Council member on Jan. 2.
