t4e.org
Foundations funding classroom technology, ministries running national programmes, and organisations working on school connectivity all name things this way. T4E reads as technology for education without a moment’s hesitation.
It also reads as training for employment or tools for everyone, the latter suiting accessibility and open-source work where broad access is the whole premise.
Three characters is close to ideal for an organisation whose name has to sit on grant applications, partner slides and conference programmes without crowding anything else out. The 4-as-for construction means readers parse it correctly without being told.
The .org is the extension those bodies use, with almost no exceptions.
The name is available. Offers welcome.
