To be certified at the Silver level, please follow this link (also linked below) to take the exam. You may only take it once in a 24 hour period. A passing score of 80% is required for Silver level.
To complete Gold and Platinum level certifications, ensure you have passed the same exam at 90% and then complete a field test under the supervision of an ABC Proctor.
Good luck!
