Does Diagnostic Math Testing Improve Student Learning?

By Julian Betts, Andrew C. Zau, Youjin Hahn

Available to all math teachers in the state, the Mathematics Diagnostic Testing Project (MDTP) offers course-specific assessments that give teachers timely feedback on their math students’ strengths and weaknesses. This report examines San Diego’s use of MDTP test results to guide the placement of students into appropriate classes or summer school. San Diego’s experiment had positive effects and could provide lessons for other districts in the state.

This report was supported with funding from the Donald Bren Foundation. The California Academic Partnership Program also provided support to the authors for related research.

PPIC Statewide Survey: Californians and Education

By Mark Baldassare, Dean Bonner, Lauren Mora, Deja Thomas

As the California Legislature considers placing a school facilities bond on the November 2024 ballot, around half of likely voters say they would vote yes on such a measure. About eight in ten public school parents see catching up academically or addressing the pandemic’s social-emotional impact as the biggest K–12 challenge.

1 in 4 Child Care Workers in California Lives in Poverty

By Tess Thorman, Caroline Danielson, Sarah Bohn

While demand for preschools and child care is high in California, the state's child care workers—particularly women of color—are poorly paid and almost twice as likely to live in poverty than workers overall.

Math Placement in California’s Public Schools

By Niu Gao, Sara Adan

Last year, the California Legislature passed a new law—the California Mathematics Placement Act—to address widespread concern over equity in the math placement process. The law is aimed at improving the measurement of student performance in order to move more students successfully through the high school curriculum. In this context, we surveyed California’s school districts during the 2015–16 school year to examine their placement policies right before the law took effect and to identify district needs for technical assistance while implementing the new law. We found that:

  • Districts need help in determining how to proceed. Because the law leaves many details open to local interpretation, many districts are unsure about how to handle certain key elements. Teacher recommendations are a good example. Our survey indicates that the majority of districts have relied on recommendations as an important factor in determining placement. But the law now restricts their use. Improving the law’s clarity is critical going forward.
  • Despite uncertainties, most districts are implementing the new law. Among our respondents, 86 percent reported having a systematic math placement policy. Sixty percent said they are somewhat or very familiar with the new law. Among these districts, 51 percent said they were already in compliance and 42 percent reported revising their policies for compliance purposes.
  • Across districts, there is a strong need for valid, reliable, and objective performance measures. This need applies both to assessing student performance and to evaluating district policies. Districts with the largest gains in student course outcomes over a 10-year period provide some insight. These districts are more likely than others to emphasize test scores, math GPA, and overall GPA when assessing student placement. They are also more likely to use end-of-year math grades to evaluate district placement policies.
  • Districts face a number of other challenges. Districts’ concerns range from handling parental expectations, to needing evidence-based performance measures, to creating better policy alignment within and across schools. In addition, equity issues and staffing shortages present ongoing challenges for many districts.

We recommend several actions for helping districts comply with the law and improve their math placement process. These include establishing evidence-based measures, refining the approach to teacher recommendations, and identifying effective placement protocols. In the longer term, districts would benefit from using student data to improve equity issues and from increased staffing, especially in rural and high-need districts.

The Impact of COVID-19 on Science Education

By Niu Gao, Kathy DiRanna, Maria T. Chang Fay

COVID-19 school shutdowns were especially disruptive for science education, which has long been a lower priority than math and English language arts. But as California schools recover from the pandemic, state policymakers can take steps to promote equitable investments in science literacy.
