When I saw online school enrollment soars in summer in the Atlanta Journal Constitution, I thought Duh! Our traffic this summer is way up. Normal enrollment pattern is Fall term peak, 90-95% of Fall term in Spring, 60% of Fall term in Summer. By contrast, our online system usage until 2008-2009 had a Spring term peak. The 2008-2009 school year showed a pattern consistent with the normal enrollment pattern in the Spring without as much drop off as expected in the Summer.
We run a higher education online learning system. The article was talking about K-12. Maybe for the similar reasons our usage is way up as well?
