This public directory covers external providers. Exam certifications, courses and memberships are labeled separately. Prices retain their currency and exam/course/subscription basis; tax, regional pricing, discounts and renewals can differ. Recognition notes cite provider descriptions or independent accreditation and partner evidence where available. Accreditation evaluates a certification process; it does not establish a hiring ranking or guarantee a job.
