Spotlight

"Isabelle was an 8th grade student with Keystone Middle School while we sailed and lived in Mexico. For her, the 8th Grade History course and Spanish I projects came alive when visiting sites throughout the country. The flexibility of the Keystone courses meant that she could catch up on work whenever we obtained internet access and it meant that she was free to immerse herself in another culture."
