Prometric

Six owners in thirty-five years, and the layer that deliberately does not write the questions it delivers.

Drake International started Drake Prometric in 1990 to run computerised testing centres. Sylvan Learning bought it in 1995 for about $44.5M in cash and stock, Thomson Corporation bought it in 2000 for roughly $775M, Educational Testing Service bought it in 2007 for $435M, Baring Private Equity Asia bought it in 2018, and EQT holds it now. Six owners in thirty-five years, for a business whose entire product is being trusted.

**The structural fact is the one most people get wrong, and it is worth stating first: Prometric does not write the exams.** Its clients develop the content, write the questions and set the passing standards. Prometric supplies secure delivery, identity verification, proctoring and score reporting. That separation is deliberate and it is the source of the industry's credibility - **the organisation that decides what competence means is not the organisation that decides whether you demonstrated it**, and neither can quietly adjust the other's work.

**Which makes one period of its history genuinely interesting.** From 2007 to 2018 Prometric was owned by Educational Testing Service - the author of the SAT and GRE. For eleven years a major writer of examinations owned a major deliverer of examinations. Nothing improper has been alleged, and ETS's own tests were not the bulk of what Prometric delivered. But the arrangement is precisely the one the industry's separation of powers is designed to avoid, and it ended: ETS sold in 2018. **The same question sits, unresolved, over the exam and credential businesses that share an owner today, and this entry notes the parallel because the site should apply its scepticism evenly rather than selectively.**

**The price arc is the cleanest illustration of a bubble on this timeline.** Sylvan paid about $44.5M in 1995. Thomson paid roughly $775M in 2000, at the height of the dot-com boom. ETS paid $435M in 2007 - **little more than half what Thomson had paid seven years earlier.** The business had not shrunk. The market's opinion of what a testing network was worth had.

A smaller detail worth keeping: ETS had sold a testing business called CapStar to Thomson for about $200M in 2004, and received it back three years later as part of the Prometric purchase. **Selling something and buying it back inside a larger deal is more common in this industry than anyone likes to admit.**

The client list explains why the stakes are higher than technology certification alone: the United States Medical Licensing Examination, the nursing boards, financial regulatory licensing, the architecture registration examination. **These are not credentials that improve a curriculum vitae - they are the ones that decide whether somebody may practise.** A delivery failure in that context is not an inconvenience.

**And delivery does fail.** The August 2023 administration of the Law School Admission Test drew widespread complaints from candidates, particularly those testing remotely. This site records that for the same reason it records criticism elsewhere: **an infrastructure company's failures are the only part of its work that becomes visible**, and pretending they do not happen would be a strange way to describe a business whose product is reliability.

**Read beside Pearson VUE the pair defines the market.** Both run global centre networks, both added remote proctoring, both deliver for hundreds of credentialing bodies, and neither writes what it delivers. The interesting difference is ownership history rather than capability: one has been inside a single education group for a quarter of a century, the other has passed through a staffing company, a tutoring chain, a media conglomerate, a test author and two private equity firms. **Whether stability or circulation produces the better custodian of other people's examinations is not a question the record settles.**
