NIH has several programs that can help you earn college credit.
DHHS Acquisition Courses: Most of the DHHS acquisition courses are recommended by the American Council on Education (ACE)for college credit. One week courses have a two credit recommendation and two week courses are recommended for 3 semester credit hours.
In order for these credits to count, you must register with ACE, have ACE forward a transcript to a participating college or university, and work with the university to meet their requirements for having the credit recognized. The forms for this process should be passed out in class.
