PLTW is an organization focused on empowering students and transforming the teaching experience – a proud tradition from the start of the organization that continues today. Since 1997, we have grown from a high school engineering program to offering comprehensive PreK-12 pathways in computer science, engineering, and biomedical science. PLTW's world-class, activity-, project-, and problem-based curriculum gives students a chance to apply what they know, identify problems, find unique solutions, and lead their own learning, rather than be passive recipients of information in a question-and-answer, right-or-wrong learning environment. In addition to our innovative curriculum, one of the most unique aspects of our programs is the engaging, rigorous professional development for teachers.We offer five programs of study: PLTW Launch (grades PreK-5), PLTW Gateway (middle school), PLTW Biomedical Science (high school), PLTW Computer Science (high school), and PLTW Engineering (high school).PLTW has 14,000 programs in 11,500 schools, serving millions students and training over 55,000 teachers.
