Massachusetts veterans who served in the armed forces anywhere in the world since June 27, 1950 and who are entitled to education and training benefits under the Korean GI Bill should give considerable thought to the goal they are seeking before signing up for any schooling or training, according to a warning issued by Manager William J. Blake of the Veterans Administration Boston Regional Office.

Blake warned that the law allows the Korean veteran but one change of course. He said that before using up any of his entitlement, the ex-GI should decide whether his goal is purely educational--such as obtaining a college degree; professional--such as becoming a lawyer; or vocational--such as training to be a steamfitter.

Within certain limits, a veteran may choose any program of education or training needed to reach the educational, professional or vocational goal to which he aspires. Also within certain limits, he may select his own school or training establishment, as long as it will "accept and retain" him in whatever field it finds him qualified for.

Blake stressed that courses in bartending, dancing or personality development are prohibited by law.
