Increasing enrollment forced Clarksburg to install four portable classrooms for the 2008–09 school year.

The Pathways in Network and Information Technology Program (P-TECH) is a dual enrollment program that enables participating students to earn both a MCPS high school diploma and an Associate of Applied Science (AAS) degree from Montgomery College for free while in high school.

Certifications will be earned in microcomputer technician and network administration in either Microsoft or Cisco or in wireless technologies.

Additionally, the program will afford participating students mentoring and a paid summer employment opportunity within the technical industry in Montgomery County.

Two shows, at least one a musical, are produced each year and have included Tarzan, Once Upon a Mattress, The Little Princess, In The Heights, and The Little Mermaid.

The team also traveled to MIT for the Lemelson-MIT EurekaFest event in 2009, having created a pressure-sensitive illuminated computer cable.

Sarah Debelius Costlow, the Signature Program Coordinator, and Paul Koda, a science teacher, sponsored the team.
