I just checked Andover's website and their new application is up. They teamed up with a few other schools in the Ten School Association (specifically Deerfield, Groton, Hotchkiss, and SPS) to offer a new online version of the candidate profile and essays.
I think its nice that more schools are switching to online applications. It will definitely take a dent out of the environmental impact that all of the applications cause, with such a large amount of applicants. It may also make submitting candidate profiles, application fees, and essays more efficient.
The application process officially begins! haha
Good luck to prospective applicants.
