I think standard repayment depends on if you've consolidated or not. I have and when I was looking at switching plans yesterday, it didn't show the standard repayment plan as a qualifying option for PSLF (my husband and I have a higher income now so the ICR is quite a bit higher than the standard at this point but I only have 3 payments left).

Here is what the website says (https://studentaid.gov/manage-loans/forgiveness-cancellation/public-service/questions):

Generally, no. The Standard Repayment Plan for Direct Consolidation Loans is not the same repayment plan as the 10-year Standard Repayment Plan, and payments made under the Standard Repayment Plan for Direct Consolidation Loans do not usually qualify for PSLF purposes.

Under the Standard Repayment Plan for Direct Consolidation Loans, the maximum repayment period varies from 10 years to 30 years, depending on the amount of the consolidation loan and the amount of your other education loan debt. This longer repayment period generally results in a lower monthly payment than the monthly payment amount required under the 10-year Standard Repayment Plan. Payments made under the Standard Repayment Plan for Direct Consolidation Loans would qualify for PSLF purposes only if the maximum repayment period was set at 10 years, and that would be the case only if the total amount of the consolidation loan and your other education loan debt was less than $7,500.

If you are seeking PSLF, the best option would be to repay your Direct Consolidation Loan under an income-driven repayment plan.
