Twenty-first-century learning requires sophisticated forms of teaching to develop student competencies, such as deep mastery of challenging content, critical thinking, complex problem-solving, effective communication and collaboration, and self-direction. Effective professional development is needed to help teachers learn and refine the pedagogies required to teach these skills, but research has noted that many professional development initiatives appear ineffective. This fact sheet answers the question: What are the features of effective professional development?

Well-designed and implemented professional development is an essential component of a comprehensive system of teaching and learning that supports students to develop the knowledge, skills, and competencies they need to thrive in the 21st century. This report details key components of effective professional development and offers rich descriptions of model programs to inform education leaders and policymakers seeking to leverage professional development to improve student learning.

Early care and education (ECE) can have a positive effect on many aspects of children’s development, including the language, literacy, mathematics, executive functioning, and social-emotional competencies needed for a smooth transition into kindergarten and later life success. But for many families, high-quality ECE is out of reach. California has established a range of programs to support the development of children from birth to age 5, but these programs are uncoordinated, insufficient in scope, and of variable quality. This report provides a comprehensive overview of the state’s ECE system, describing its administration and funding, access to care, program quality, and data limitations.

The Every Student Succeeds Act provides an important opportunity for states to broaden the definition of student success to include measures of students’ social-emotional, as well as academic, development. This brief describes how states might measure and promote social and emotional learning (SEL) in their accountability and continuous improvement plans.

How can schools be encouraged to help students develop socially and emotionally and to foster positive school environments in the context of new accountability under the Every Student Succeeds Act? This report provides a framework for considering how measures of social and emotional learning (SEL) and school climate may be incorporated into an accountability and continuous improvement system.

Under the Every Student Succeeds Act (ESSA), state assessment systems must be designed to measure higher-order thinking skills and understanding. This report, published in partnership with the Council of Chief State Schools Officers (CCSSO), details how states can use performance assessments—including portfolios, projects, and extended-performance tasks—to assess what students know and are able to do.

Turnover accounts for 90% of the demand for new teachers, exacerbating shortages and undermining academic progress. This brief summarizes research on the important role that principals can play in reducing the steady churn of teachers and highlights actions states and districts can take to strengthen school leadership.

Principals play a central role in creating schools in which students thrive academically and the teaching staff is strong, stable, and supported. This report analyzes the research on quality preparation and professional development programs for principals, highlighting examples of effective programs and providing guidance for policymakers.

Improving student achievement requires strong school leadership. Principals also play a critical role in addressing widespread teacher shortages by creating school environments that attract and retain competent teachers. This fact sheet summarizes key elements of high-quality and effective preparation and professional development programs designed to enable principals to improve student and school outcomes.
