Here is the definition of provisional accreditation:

Provisional Accreditation – Provisional accreditation is granted to new programs in veterinary technology where students have not completed the entire curriculum and/or the programs have not produced sufficient numbers of graduates to adequately assess outcomes. Programs may remain on provisional accreditation for a period not to exceed five years. A classification of provisional accreditation is not punitive. Graduates of a provisionally accredited program are graduates of an AVMA-accredited program.

As CathyBogart suggested, check out their exam pass rates also.

But this is good to find out all this information before investing the time and money to enroll and then find out.
