The video highlights the importance of mentorship programs for new teachers. It notes that without guidance, nearly 50% of teachers leave within 5 years, costing billions and disrupting student learning. The Hillsborough County School System addresses this by pairing new teachers with mentor teachers who provide support. The mentors observe classes and offer feedback to help new teachers improve and help retain them long-term. When properly implemented, mentorship programs can significantly reduce teacher turnover and create stability for students.
