Cheapest grad schools per credit

[Ideas]

I don't understand 

wouldn't that be double counting the grad credits ? 

if you use them as part of the undergrad degree then they go in as upper level undergrad don't they ? 
how can you use them again as grad credits to be able to teach ?

when you apply for a teaching job aren't they're going to request transcripts from all your schools ? 

it just seems weird

I figure it's like if someone gets a IT certification, and a school gives them undergrad credit for having it. They can still "use" the certification by telling the employer that they have it. It doesn't get used up because they got some undergrad credit for it.

In this case, someone would attend a school like FHSU and get 18 grad credits. Then just because COSC allows them some undergrad credit, it doesn't mean they can't say "I did grad credits at FHSU", because they did those credits and the employer can see the FHSU transcript. 

I'm not saying the grad credits get used again in a second degree.

Maybe a school would notice that some of same credits were used within the undergrad degree. I don't think they would care, but I'm not an expert in this, having never applied to teach.

Personally, getting an adjunct position is not a priority for me anymore. I might try if I get 18 in an area, but I'm not sure I'll have the time.
