Carol Schwartz, a member of the D.C. school board, has been named to a White House post as acting associate director of the Office of Presidential Personnel.

Schwartz, who has represented Ward 3 in Northwest Washington on the board for six years, began working Wednesday, the first full day of President Reagan's administration, at the personnel post, which she said pays about $47,000 a year.

Schwartz, an active Republican who worked on the presidential transition, said she expects to continue serving on the school board until her current term expires at the end of the year. She said she did not know if she would seek re-election to the board post, which pays about $19,000 a year.

Her appointment appears to be one of the first of its kind in the new administration for Republicans from the District.

She said she saw no legal conflict between service on the school board and in the White House post, which she said is designated "acting" until all clearances are completed. "I think I'll be able to contribute as much as anyone else" on the board, she said. "I'm still very much committed to the children of this city."

Schwartz, the mother of four children, holds a bachelor's degree in elementary and special education from the University of Texas, and was named by President Ford in 1974 to a national advisory council on education of disadvantaged children.

As one of four associate directors, she said, she will be involved with finding top level appointees for the Justice Department and 31 regulatory agencies.
