How many credits do you need for masters in counseling?

There is no single answer, because different schools will have programs that differ to one extent or another. Most programs of this kind are designed to be completed in two years. The best thing to do is research schools that offer the degree you are interested in, and compare them in terms of the amount of time it will take to earn the degree, what kind of internship experience is required during the program, what kinds of prerequisites there are if any, and costs. Some programs are more flexible in terms of the total time that is allowed during which to earn a degree, and some are less flexible. I general, there are at least two different 'tracks' that you can take. You can get state credentials as a counselor by earning the MSW, a masters degree in social work, or by earning a degree in counseling that leads to the LMHC, licensed mental health counselor.
