Project Lead The Way (PLTW) is a nationally recognized organization that develops rigorous STEM curricula for use by elementary, middle, and high schools. PLTW also provides professional development training for instructors. Many Harmony teachers attended the training at the UT Tyler Houston Engineering Center (HEC) and completed trainings in Computer Integrated Manufacturing, and engineering. Trainings are offered during the summer time, and offer teachers certifications among STEM divisions. PLTW has helped Harmony educators learn top teaching techniques to provide our students with 21st century skills they will use after high school.
