Unfortunately, it seems that many careers that have been popular with yeshiva guys have become overcrowded. Law is one. If you go to law school you have to go to a really good one or get really top grades in order to get a decent job. Accountancy is also one of those “easy and light” fields that attracts an overabundance of frum students. Computer-related fields may be growing, depending, but you’ll need computer expertise (not just knowing what key to push) for any job nowadays. Stay away from for-profit schools. They take your Pell Grant and frequently don’t tell you that most of their graduates don’t get jobs.
Get professional job counseling before you spend any money. Agudah has Project Cope in New York, Baltimore has Joblink, and if you don’t live in either area, I’m sure if you call them they’ll give you contacts in your area. Don’t let anyone talk you into spending money until you’ve thoroughly checked out the job prospects for the field and the employment rate of the graduates of the school. “Asking around” is a good way to get information that’s misleading because people only have the knowledge of their personal corner of the job market. Get advice from the frum pros. That’s what our kehillahs pay them for, and they’ll help you find the field that suits your interests and will make you a respectable parnassah.
