All About TSTM Essentials

TSTM Essentials is an updated, highly interactive version of American Institutes for Research (AIR)’s national Teaching Skills That Matter training initiative, which we have redesigned especially for our programs in New Mexico. Our state was first invited to participate in AIR’s national TSTM Cohort Training in 2020-21, and an initial group of four instructors applied to join professional development lead Tina Hite and colleagues from across the country on an 8-month learning journey into the TSTM content, skills, approaches, and implementation. Upon successful completion, we were tasked to bring TSTM to New Mexico adult education.


Over the past few years, our New Mexico Team has found that the Nine Central Skills and the Three Instructional Approaches have been especially valued by our instructors. In 2024, the TSTM Essentials Team (Nina Bar-Giora, Bill Hladky, Meriah Lira, and Rebecca Sherry) incorporated our experiences and feedback from the field to completely redesign the delivery of these TSTM components so that each one is now a hands-on workshop. The workshops do not need to be completed sequentially, and they no longer need to be completed in a single semester. Instructional coaching provides optional, short-term practice and feedback on one component at a time immediately following the workshop. Although the TSTM Toolkit is still available to offer excellent example lesson plans, our Essentials goal is to work with you to seamlessly integrate TSTM components into your existing curriculum. We are excited to see your creativity!
