No I would not have my kids do the TB test. It's an injection.
Have you lived with homeless people? Worked with homeless people? Been exposed to TB in any way?
Know that if you want to volunteer or work in the classroom, you have to have one. I had the injection (and we VERY selective about vaccines) in 2006 and my Left Arm still does not feel right. There is a faint tingly sensation still! I called my doctors office where I got the shot and they said at first "you are the first person who has ever complained about this" and on another call the person who answered the phone said "oh, my friend said the same thing." I never made an official report, so I have to wonder how common this is.
So at the time in a panic I went online searching for information. That's when I found out there indeed was an alternative to the shot. Now, there is new, more accurate blood test that the CDC is saying is better. QUANTIFERON TB GOLD TEST

Unfortunately, it costs more. And you might have to have to mail for it and find a blood technician to help you.
So if you have to I would do the Quantiferon TB Gold test. Thankfully that option exists.
As far as the Oral assessment, isn't there a waiver for that too? I thought there was. I could be wrong. Call around town and find out how much pediatric dentists charge. I would definitely take them in for exams because they periodically clean the teeth, check for trouble spots and it's generally a good thing. My children started going around age 3. Ask your mommy friends which dentists they like. Take a tour of the place by yourself to see if you like it.
They will probably need a health exam before entering school. I don't know how you can get around that. Are there any vax friendly peds in your area? Go to mothering.com/discussion board and visit the Find Your Tribe and ask the moms in your area there. There is also an active vax board there that can help you.
