The Inter-American Teacher Education Network (ITEN) is an initiative that works with Ministries of Education or other governmental teacher education institutions of OAS Member States and classroom teachers to advance the teaching profession in the Western hemisphere. During its fourth phase, ITEN focused on promoting collaborative work to solve regional policy and practice issues related to pre-K-12 teacher education in STEM (science, technology, engineering, and mathematics). This focus on STEM education helps support teachers in key areas, close the gender gap for girls and women, and address the technology needs of growing economies.
