Yes. You may take the CRCST exam as a Provisional candidate.
However, you must submit documentation of your hands-on experience, completed on a paid or volunteer basis, within six months of passing the exam.
During that six-month period you will be considered Provisionally Certified.
If you are unable to submit the documentation within the six-month period, your certification will be revoked. Therefore, we highly recommend that you have a location to complete your hours secured prior to testing.
