NAACP officials urged President Carter yesterday to support the Humphrey-Hawkins bill, which would mandate a reduction in unemployment to 4 per cent, but received no assurances.

Carter spent about 30 minutes meeting with Benjamin Hooks, the association's new executive director, and other leaders of the civil rights organization.

In the past, Carter has endorset the concept of full employment embodied in the bill but has said he wanted to further study some of the aspects that commit the government to provide jobs at last resort.

The President, in a speech to the Congressional Black Caucus Saturday night, said his administration's proposal to reduce unemployment would be announces soon.

Carter has been criticized by black leaders for what they say is his failure to live up to his campaign commitments to blacks.

Hooks warned that if his organization is not satisfied with administration programs, it will not hesitate to "demonstrate, picket or boycott."

But, he said, Carter has been showing "a very deep concern about the fact that blacks are trying to move forward."

However, he said, while Carter has increased the number of blacks and other minorities in government jobs, "we don't feel we've gotten enough appointments."

The black leader said the group told the President to remember human needs as he shapes the federal budget with the goal of balancing it by 1981.

Hooks said the group only had time to discuss a few of the 18 or 19 items about which it is most concerned, but that the leaders are planning to go over the details of their proposals with Cabinet members and their aides.
