In the conference call, the company said it was seeing weaker demand from such clients as they cut spending on education budgets. Many for-profit educational institutions, which use the services of QuinStreet, have been hit by the U.S. Department of Education's (DOE) regulation on gainful employment that determines whether for-profit colleges qualify for federal student aid, according to a Reuters report. Many colleges were seen to be at risk of losing access to federal aid based on the proposals by the DOE which are expected to take effect on July 31, 2011. QuinStreet said the pricing environment has 'hardly improved' and was disappointed by its first-quarter growth which is expected to be flat.
