my daughter has a credit score of 595 but she did straighten out the problem that would've brought up her score, it's been app. 3 mos. since this happened, and still her credit score is the same. How long does this take for her credit score to adjust and secondly would she still be able to qualify?

The MFA is not a credit reporting agency. The only thing we can tell you is that the Bureau updates every 30 days. If you have not seen an update you would need to contact the credit bureau to check the stauts.
