Why choose a technical school and not a private one?

Hi,

I have been looking at job boards to see the job market for CNA and PCT and I see on some of them they specify tht they want a certification from a technical school... Why is that? I was looking at this school www.ecrga.com and I talked to the admissisions rep and she says they are a technical school, but they are also private. They do not offer Pell grant but they have financial assistance through the government call WIA or something like that to help with financial aid...but Im just curious, if I choose this school will I be able to find a job...the school is accredited, so...I dont understand what the difference btwn a private and technical school would be from an employers viewpoint..thanks so much in advance for ur insight or input or 2 cents
