The Reagan administration plans to abandon the traditional written examination requirement for civil servants and allow college graduates with high grades to be hired immediately, The Washington Post reported Thursday.

The planned changes, expected to be announced Thursday, would come six years after the government's entrance test for workers was thrown out as racially discriminatory.The Post said applicants for entry-level professional and administrative positions can be eligible for a job by:

-Earning a college grade point average of at least 3.0 on a scale of 4.0 and impressing an agency recruiter with personal, technical or other qualifications, or;

-Passing a job-related skills test and a new kind of exam known as the Individual Achievement Record, which would measure "the full range of relevant personal qualities required for successful job performance."
