Tek Essentials Diver in worldwide: 23 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 15 publish course prices.
TecDiveTools lists 23 dive centres teaching Tek Essentials Diver worldwide. 15 of them publish course prices, in the currency the shop advertises and with the date each was checked — not converted, and not estimated.
Listings are ordered by how much evidence exists about their technical diving, not by a star rating, with any paid Featured listing shown first and marked as such (how rankings work). 12 of these 23 carry reviews we have read and classified as being about technical or overhead training. The count excludes recreational certifications by name, so a busy resort does not outrank a one-instructor cave operation on the volume of its reef trips. Separately, 14 have at least one instructor whose reviews we have read and summarised — a dive centre carries no synthesis of its own. How we read and count reviews.

At the same tier in TecDiveTools' cross-agency comparison, dive centres worldwide also teach TDI Intro to Tech (188) and SSI XR Extended Range Foundations (1). They are comparable rather than interchangeable — each agency sets its own standards and card, so check which one your next course accepts.
