It now appears you can sign up for EPGY Open Enrollment on your own...
I emailed EPGY yesterday about the Open Enrollment Program because it looked like they made some changes to the online enrollment page, now allowing anyone to create a group with no minimum number of students. I just got an email back confirming there is no longer a minimum number of students required for Open Enrollment, so anyone can start a 'group', even for his or her own child. Here is the exact wording I received from EPGY:
"Yes, we recently changed our policy removing the minimum number of members requirement for starting an Open Enrollment group. Anyone can start a group just for their own child or children, if they want."
Hopefully this will make the program more accessible to people.
