York Suburban Senior High School (York, PA). Beyond the classroom, the Trojan Learning Center was developed to provide supplemental assistance with day-to-day coursework, along with more intensive assistance. The center is led by a full-time staff member who assists students with content and organizational skills while also providing academic monitoring. The students are further supported by at least one additional teaching staff member each period, along with National Honor Society students who provide student tutoring. The center remains open after school to provide support to those students who are unable to access it during the day. While the center is always available on a voluntary basis, students are also assigned to the center based upon their past progress. Freshman students are assigned mandatory hours outside of school when they demonstrate consistent difficulty with a class or classes. Each year, more than 40% of the freshman class use the center in some fashion, and many students continue to use it as they move on to higher grade levels. Through purposefully designed instructional activities, a mastery approach to learning, and supplemental interventions, we are able to meet the diverse needs of students and help them meet our instructional goals.
