Leaders in professional learning

The Teachers Teaching with Technology™ (T3™) professional learning organization is comprised of some of the most creative and innovative mathematics, science and STEM teachers in the world. They are successful educators who work with teachers and students from elementary grades through the university level.

As advocates for enhancing student achievement, T3™ instructors speak from current experiences involving technology, educational trends and pedagogical practices. Their backgrounds include public, private, charter and magnet schools, as well as urban, suburban and rural environments.

For more than 35 years, the T3™ organization has paved the way in professional learning. It has grown to include over 300 instructors in North America and hundreds more around the world. T3™ instructors work with over 60,000 educators a year in North America alone.

Apply to join a T3™ Teacher Leader Cadre

While some districts may offer a T3™ TLC program, there are also opportunities available every other year to join a TI-hosted T3™ TLC. Participation is limited and determined via an application process.

In 2024, TI will host two T3™ TLC programs. These begin with an in-person component, followed by online meetings comprised of the equivalent of nine days of professional learning.

In addition to our standard T3™ TLC, we are offering a special T3™ TLC in partnership with Vernier Science Education® and its Trendsetters Community. The specific details for each T3™ TLC and the application can be found by following the links below.
