Yoga Alliance credentials show up everywhere in teacher training marketing — RYS, RYT, RPYS, RCYS, YACEP — often without much explanation of what any of them actually mean or require. None of them are government licences, and Yoga Alliance doesn't accredit curricula in the way a university accreditor would. What it does is maintain a public registry of schools and teachers who have attested to meeting its published hour and content standards. Here's what each credential actually represents, what it takes to earn, and what it doesn't guarantee.
What Yoga Alliance Actually Is
Yoga Alliance is a US-based, non-profit membership and registry organisation for the yoga profession. It isn't a licensing body — nobody needs a Yoga Alliance credential to legally teach yoga anywhere, including in the United States or India — and it doesn't inspect or accredit training content the way an academic accreditor does. What it provides is a published set of minimum hour and curriculum-category standards, organised under Educational Categories such as Techniques & Training, Anatomy & Physiology, Yoga Philosophy, Professional Essentials and Practicum, plus a public registry where a school or teacher's current standing can be checked. Its value is mostly reputational and structural: a recognisable baseline that students, employers and studios can reference, and a registry that makes false claims about certification relatively easy to check.
RYS: Registered Yoga School
RYS (Registered Yoga School) is the foundational school-level credential and the one most teacher trainings advertise. Yoga Alliance currently issues RYS credentials at several hour tiers — most visibly RYS 200 and RYS 500 — reflecting the minimum contact hours a school's foundational training must deliver across the required educational categories. A school holding RYS 200 status can award graduates the standing to apply for RYT 200 (Registered Yoga Teacher, 200-hour); a school holding RYS 500 status — either through a single 500-hour training or a registered 200-hour plus an approved continuing 300-hour pathway — supports the RYT 500 level. The school is what's registered; a graduate then separately applies to Yoga Alliance for their own individual RYT registration.
RPYS: Registered Prenatal Yoga School
RPYS (Registered Prenatal Yoga School) is a specialty school credential for prenatal yoga teacher training, sitting alongside — not instead of — a foundational RYS credential. Under Yoga Alliance's published standards, RPYS registration requires a training of at least 85 hours specifically in prenatal yoga content, and a teacher applying for the individual RPYT (Registered Prenatal Yoga Teacher) credential needs to already hold an RYT registration, complete that RPYS training, and log at least 30 hours of prenatal teaching afterward. In practice this means a genuinely qualified prenatal specialist has typically completed a foundational 200-hour training first, then a dedicated prenatal specialisation on top of it — which is why programmes that compress "prenatal certification" into a weekend, with no foundational hours behind it, are worth looking at more carefully.
RCYS: Registered Children's Yoga School
RCYS (Registered Children's Yoga School) works on the same logic for children's yoga. Yoga Alliance's published standard requires a minimum of 95 hours of children's-yoga-specific training at an RCYS school, and an individual applying for RCYT (Registered Children's Yoga Teacher) status needs at least 30 hours of children's yoga teaching after completing that training. Children's yoga has its own considerations — attention span, developmentally appropriate sequencing, classroom management, safeguarding — that a general adult-oriented 200-hour training doesn't cover in depth, which is the rationale behind a dedicated specialty credential rather than folding it into a foundational programme.
YACEP: Continuing Education Provider
YACEP (Yoga Alliance Continuing Education Provider) is a different kind of credential — it's for individual educators or schools offering shorter continuing-education courses and workshops to teachers who are already certified, rather than a full foundational or specialty teacher training. All Experienced Registered Yoga Teachers (E-RYTs) are eligible to hold YACEP status, and continuing education hours logged with a YACEP provider count toward an RYT's ongoing continuing-education requirement to maintain active registration. A course like Hormone Yoga Therapy, aimed at teachers who already hold a foundational certification and want to add a specific therapeutic skill set, typically sits under this category rather than under RYS.
RYS vs RYT: Schools vs Individual Teachers
It's worth being precise about who holds which credential, because marketing sometimes blurs the two. RYS, RPYS, RCYS and YACEP are all credentials held by a school or provider — they describe an organisation's registered status to deliver training that meets Yoga Alliance's standards. RYT, RPYT and RCYT are credentials held by an individual teacher, earned by graduating from an appropriately registered school and then applying to Yoga Alliance directly. A school can be a legitimate RYS 200 provider while an individual teacher who trained there chooses not to register as RYT (registration is optional and involves its own fee) — so "trained at an RYS school" and "is a registered RYT" aren't automatically the same claim, even though they usually go together.
What a Credential Doesn't Guarantee
None of these credentials are a guarantee of teaching quality, safety awareness or how well a programme is actually run day to day — they confirm that a minimum hour count and category structure exist on paper, verified by the school's own attestation and Yoga Alliance's periodic review process, not a direct classroom inspection. They also don't confer any legal right to teach; that's determined by local law (which in most countries, including India, does not currently require any yoga-specific licence) and by individual studios' or employers' own hiring standards. Registration status can also change — a school's RYS standing can lapse or be revoked — so a credential a school held two years ago isn't proof of current standing.
How to Verify a School's Standing Yourself
Yoga Alliance maintains a searchable public directory of currently registered schools and teachers at yogaalliance.org. Before enrolling anywhere, it's worth searching the school's name directly in that directory rather than taking a website badge or logo at face value — badges can be outdated, or occasionally used by schools that never held the credential they're displaying. The directory listing will show the specific credential type (RYS 200, RYS 500, RPYS, RCYS, YACEP) and, where relevant, its current status, which is the most reliable single check available to a prospective student.
Stri Wellness holds Yoga Alliance RYS registration for its foundational and specialty trainings, including our 200-Hour Yoga Teacher Training for Women (RYS 200), 100-Hour Prenatal & Postnatal and 100-Hour Kids Yoga programmes. You're welcome to verify our standing directly in the Yoga Alliance directory before enrolling.

A Yoga Alliance credential is a useful, verifiable baseline — but it's a floor, not a ceiling. Two RYS 200 schools can deliver very different quality of teaching, mentorship and practicum feedback while both meeting the same minimum hour count on paper. When comparing programmes, treat the credential as one filter among several: verify it directly in the registry, then look past it to faculty experience, practicum structure, class sizes, and how specific the specialty content actually is for what you want to teach — prenatal, children's, hormone health, or otherwise.
