Certified Meditators

Could have a meditation certification course,
where a with an EEG a persons brainwaves are monitored for a certain period of time,
and assuming the average is at a certain level they can be certified for that level of meditation.

There would be at least 4 certificates, being Alpha, Theta, Delta and Gamma, perhaps once a person has done all four, they could get a Master Meditator certificate (with a test asking the meditator to meditate at a particular frequency and then seeing the result on the EEG for a certain period of time).
