Three characters, .org, X-to-Y. P2T reads as prison to training, policy to practice, or pilot to scale, though that last one stretches the letters.
Policy to practice is a phrase used constantly in public health, education, and social research. It names the gap everyone complains about: the distance between what the evidence says and what institutions actually do. Organisations, journals, and programmes dedicated to closing it exist in every one of those fields.
Prison to training and the wider family of reentry programmes is another strong reading, and those organisations are overwhelmingly nonprofit.
The X-to-Y construction is what makes this readable. Three letters alone are an abbreviation. Three letters with a preposition are a statement about direction, and a reader completes it without effort.
Three characters on the .org, permanently scarce, correctly matched to an institutional buyer.
The name is available. Offers welcome.
