Yoga teachers advertise qualifications expressed in hours, and those numbers come from a voluntary system rather than a professional licence. The distinction determines what a credential can tell a prospective student.
The profession is largely unregulated
In most countries anyone may teach yoga without a licence, because the activity is not classified as a regulated healthcare or education profession.
No statutory body sets a curriculum, examines candidates or maintains a register with the power to remove someone from practice.
Standards therefore emerged from membership organisations, which schools and teachers join by choice and which depend on fees rather than statute. Their sanction for a breach is removal from a directory, not removal from practice.
Hours are the unit of measurement
The familiar figures refer to contact hours in a training programme, distributed across technique, anatomy, philosophy, teaching methodology and practicum.
A registry specifies how those hours must be allocated and what topics must be covered, and approves schools that submit a conforming syllabus.
Because the standard describes inputs rather than outcomes, two graduates with identical hours can differ substantially in what they can actually do.
Assessment varies between schools
Some programmes require observed teaching, written examination and a period of supervised practice before certification.
Others certify on attendance, and the registry standard does not compel a particular level of assessment rigour.
This is why the reputation of the specific school carries more information than the registry designation attached to it, and why asking how a trainee was assessed is a more revealing question than asking how many hours they completed.
Format compression is a real variable
The same number of hours can be delivered over an intensive month or across a year of weekends, and the two produce different learning.
Extended formats allow trainees to teach and return with questions, which is where much of the practical skill develops.
Intensive formats suit people who cannot commit weekly time, and the compressed schedule leaves less room for accumulated practice between sessions. Neither is inherently better, but the registry treats them as equivalent when they are not.
What to check when it matters clinically
Additional training exists for pregnancy, older adults, injury and mental health contexts, and these specialisations vary widely in depth.
Teachers working with medical conditions should be able to describe their specific training and, importantly, when they refer a student on.
A teacher who offers to treat a diagnosed condition is working outside the scope of any yoga qualification, and conditions requiring treatment belong with a registered healthcare professional.
