As of the 2006-07 school year, Middletown High School will be using the Chemistry in the Community ("ChemCom") program developed by the American Chemical Society for all high school students.  Additionally, this course will be aligned with the Rhode Island Grade Span Expectations to prepare for the Rhode Island State Science Test ["NECAP"] that has been administered beginning in 2008.
