All the private LPN schools will run you $30K or more! I have several coworkers that went to Bullard-Haven's Tech for their LPN and they are great nurses. I went to a private LPN school as did several of my coworkers and we are just as good a nurse as the State Tech nurses.
Just know that the LPN jobs in CT have dried up significantly, few and far between and most want experience. Honestly there aren't many advancement opportunities. Most LPN's in CT are in the LTC setting, some in offices/clinics. If you really want advancement opportunities, more available jobs (then again ALL nursing positions in CT aren't nearly as abundent as they were 4 or 5 years ago) go for your RN.
I'm not trying to be a Debbie Downer or dash your hopes/dreams, its just that many on AN have stated they weren't aware of the limited job opportunities of the LPN or of the job shortage.
If you decide to do the LPN route, make sure you find out about that schools NCLEX pass rate and make 100% sure they are accredited! You can check with the CT BON for accredited schools.
