The school offers Advanced Placement classes as well as the University of Minnesota-affiliated College in the Schools program. In 2002 the school received a grant from the Bill & Melinda Gates Foundation which led to the introduction of Small Learning Communities. Johnson offers over 40 extracurricular clubs and organizations including an Air Force Junior Reserve Officers' Training Corps (AFJROTC) unit, one of only three in the state. The school currently competes in the Saint Paul City Conference. The school's hockey team has had success, winning four state titles, but in the last decade has suffered from low participation.
