The loan forgiveness program can forgive loans under the Direct Loan Program. Private loans are excluded. Also, other Education Department Loans such as Perkins, FFEL, etc. are not qualified.
If you’re able to consolidate your non-Direct Loan Program into a Direct Consolidation Loan, the consolidated loan that resulted will be eligible for the government employee student loan forgiveness . But you have to remember that the forgiveness resulted is contingent on making the 120 payments.
You can find out the types of loans you have by finding out from the National Student Loan Data System. Visit the studentloans.gov to know more about the consolidation of your loans.
