Grouping by Ability Of Students Upheld For New York City

The Federal Government said yesterday that New York City public schools could continue grouping Youngsters by ability even if it led to racially imbalanced classes.

And in a related action, it withdrew a charge that the city’s three academically elite high schools discriminated against black and female students.

The Government actions, contained in an agreement with the Board of Education, resolve a complaint intitated by the Federal Office for Civil Rights in early 1977.The board is expected to make the agreement public today.
