To earn an RDMS, RDCS, RVT, and RMSKS credentials, you must pass the SPI examination and a corresponding specialty examination within five years. After passing the SPI examination, you can earn additional credentials without having to retake the SPI examination, provided you maintain active status.

The SPI examination fee is $225 USD, which includes a $100 USD non-refundable processing fee.
