Registration is going on now for up to 30,000 federally and city-funded jobs that the city will try to provide this summer for District youths from 14 through 21 years old, according to a recent announcement by Mayor Marion Barry.

In past years, fewer than 20,000 jobs have been available through the District's summer youth job program.

Acting D.C. Labor Department Director Matthew Shannon is urging youths from low-income families to register early so they can receive priority consideration for available jobs. Under new federal requirements, Shannon said, the city must vertify the incomes of families whose children apply for prority consideration.

The District is expected to receive between $8.5 and $11 million in federal funds to provide up to 15,000 jobs in District government and nonprofit agencies for the lowest-income youths. In addition, the mayor is seeking congressional approval to spend $11 million of city-appropriated funds to provide another 15,000 jobs, and to initiate a program of year-round youth employment opportunities.

Several hundred District jobs are available for qualified young people through regular summer hires, which is a college work-study program with expenses jointly shared by the college, the city and the Youth Conservation Corps.

The federally funded jobs are reserved for youths from low-income families. While the other jobs would go to young people from families at a variety of income levels, top priority will be given to those from low-income families; and second priority to those from families with incomes slightly above the federally set low-income levels.

To qualify for top priority, young people would have to be from families with maximum incomes ranging from $4,580 for a family of two to $21,560 for a family of 13.

Hours for most of the summer jobs will range from 20 to 25 a week, and some regular summer hires will be 40 hours. Wages for most jobs will be $2.90 per hour, the federal minimum wage.
