O.L. Davis Jr. has assumed the presidency of the Association for Supervision and Curriculum Development for 1982-83.
Mr. Davis, a professor of curriculum and instruction at the University of Texas at Austin, says he views proposed tuition tax credits for the families of private-school students as "a threat to freedom."
"ascd's primary service is to improve schools," the new president says, "and not to support any kind of move which would have the effect of withdrawal of support of public education."
The association, whose 36,000 members come from both public and private schools, has taken an official position opposing tuition tax credits, according to a spokesman.
George J. Rios, a vice president of the Equitable Life Assurance Society of the United States, has been appointed deputy director of the Education Department's office of bilingual education and minority languages affairs.
Mr. Rios, a native of New York City, previously served on the New York police department's civilian complaint-review board and has been active in Hispanic community causes.
He holds a master's degree in public administration from the City University of New York.
He will assume his new position on June 11.
