Advanced Art History Class Becomes a School Favorite When Corrington High School decided to create an AP art history class, no one knew if the class would be a success. The first year, 2004 didn't hold much promise when only five students
signed up for the class. However, Mrs. Peters dedicated herself to teaching art history to those five students. The class got to go on field trips to art museums and galleries. Mrs. Peters made
learning about art fun. At the end of the school year, all five students passed the AP exam.
The next year, Mrs. Peters had 11 students sign up for the class. Most of them signed up because they heard good things about the class from the first five students. The class had fun but
proved that they learned a lot when, yet again, the entire class passed the AP examy
Mrs. Peters' reputation increased the interest in the class. In 2006, 29 students syned up for the class. The two years after that, Mrs. Peters' class was filled to capacity at 33 students. In the past
three years, the passing rate for the AP art history exam was 98 percent today the art history class that began five years ago achieved its popularity through the teachers hard work and the students success
