If you default on your federal student loan, the loan may be placed with a collection agency, which will then contact you to obtain payment. 
If you default on your federal student loan , the entire balance of the loan principal and interest becomes immediately due. This is called acceleration. Once your loan is accelerated , you no longer have access to deferment or forbearance options or to a choice of repayment plans. In addition , if you do not make repayment arrangements with the holder of your loan the U.S. Department of Education ED, a guaranty agency, or the school that made the loan and comply with the terms of the repayment arrangement , your loan holder may place your loan with a collection agency.

Many guaranty agencies also contract with collection agencies for the same reason. Collection agency employees are trained to comply with the terms of the Fair Debt Collection Practices Act, which govern collection practices by debt collectors.
