"Schools' First and Forever Responders: Preparing and Supporting Teachers in the Time of COVID-19" elevates a rationale and considerations for evidence-based strategies and innovative approaches to support teachers and teacher candidates during and following the COVID-19 crisis. Because teachers are the most vital in-school education resource, supporting the teacher workforce through the disruptions created by COVID-19 is essential to ensure continuity of learning for students. As schools and districts rush to meet immediate workforce needs, longer term planning is critical in light of looming budget declines. For each of the considerations highlighted in the brief, we cite research or examples from other states and districts that can be helpful to learn more and guide decision-making.
