A college education. considered to be a ticket to a good job in the 1950s and 1960s, may buy passage to vocational frustation in the late 1970s and early 1980s, according to a Labor Department job outlook released yesterday.

The Occupational Outlook Hand book estimates that "the vast majority' of the 46 million jobs that will open up between 1976 and 1985 'will require less than four years of college training.'

In recent years, Labor Secretary Ray Marshall noted in a statement, 'more and more graduates have been forced to enter jobs not traditionally sought by college graduates.'

The Labor Department lists a host of employment areas that will grow faster than average which do not require college degrees.Among them are 'insulation workers, police officers, waste water treatment plant operators, most subprofessional health occupations (nursing aides, orderlies and nursing home attendants), nechanics' and repairmen.

The department also cities bookkeepers, cashiers, secretaries and typists as workers who will face food opportunities 'since these fields are large and employe turnover is high.'

Over the 10-years periodfrom 1976 through 1985, the economy will create 17 million new jobs abd 29 million workers who die or retire will have to be replaced, the agency estimated.

Among profesions to avoid are teaching, which is already severely over crowded, newspaper reporting and law.

Although the number of law job faster than average, there will be 'keen competition' for salaried positions.

Physicians will continue to have little difficulty finding jobs, while demand foe dentists will grow at an average pace.

Clerical workers make up both the largest and the number of service workers will grow quickly, too, reflecting rising demand for medical care and 'custodial and protective services.'

The department noted that 'rising levels of income should cause more frequent use of restaurants, beauty salons and leisure services.'

Although there will be rising denmand for economists, those who want academic posts will find it difficult. Overall, university teachers will find it hard to get jobs and those without a doctorate will face even more difficulty in getting a teaching slot.

Kindergarden, elementary and secondary education teachers will find it jobs scarce; teachers in these fields who left temporarily will find themselves in stiff competition with new graduates.

Printers will face a declining market as computers take over type-setting, but lithographers will see a growing demand for their services as off set demand for their services as offset printing replaces letterpress printing.
