EPGY is now giftedandtalented.com. EPGY did have programs for schools and was used by many schools. I'm not sure if giftedandtalented has continued with those contracts. EPGY also had tools which gave teachers feedback on students' performance and the ability to adjust settings according to students needs.
You can contact g&t to see if they still offer school programs. If you PM and e-mail address, I can send you the EPGY teacher's manuals if you'd like to see them and ask g&t about what features are still available.
