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.

California’s Historic Corrections Reforms

By Magnus Lofstrom, Mia Bird, Brandon Martin

California has dramatically lowered incarceration—by about 55,000 inmates since 2006—with no broad increase in crime. But recidivism rates remain high and corrections spending continues to rise.

California’s County Jails in the Era of Reform

By Sonya Tafoya, Mia Bird, Ryken Grattet, Viet Nguyen

California’s county jails have been profoundly affected by several reforms over the last decade. Most importantly, in 2011, public safety realignment shifted responsibility for large numbers of non-serious, non-violent, and non-sexual offenders from state prisons to county correctional systems. This lowered the state prison population—allowing prisons to prioritize beds for more serious offenders—but increased county jail populations. Three years later, Proposition 47 downgraded a range of drug and property offenses from potential felonies to misdemeanors. The reduced population pressure has allowed jails to prioritize beds for more serious drug and property offenders who are no longer eligible for prison.

Despite the growing importance of jails, little is known about the basic characteristics of jail populations. In this report, we analyze state and local data on individuals moving through county correctional systems. Using data from 11 counties, we find that:

  • Reforms altered the offender composition of the jail population, especially among those held on drug and property crimes. After three years under realignment, the number of drug and property offenders in jails increased by 55 percent and 40 percent, respectively. One year after the passage of Proposition 47, the number of drug and property offenders fell by 35 percent and 13 percent, respectively.
  • Length of stay for felony drug and property offenders increased after realignment. For example, median time served for felony drug offenders released in October 2011 was 45 days, compared to 98 days for those released in October 2015. However, length of stay for people who served time for misdemeanors and felony crimes against persons has remained stable.
  • Releases due to overcapacity rose under realignment and dropped after Proposition 47, when jail population pressure eased.
  • The demographic composition of jails has largely remained stable. But the age distribution does show modest signs of change: the share of those ages 18–21 in jail has decreased slightly, as the share of those in their 30s has increased.

As jail populations shift toward more serious drug and property offenders, counties and the state will need to consider how jail security and rehabilitative programs might be made more effective. While researchers and policymakers continue to examine the longer-term effects of realignment and Proposition 47, it is also important to keep in mind that the recent reprioritization of jail beds may have implications for crime and recidivism.

What to Expect from California’s New Motor Voter Law

By Eric McGhee, Mindy Romero

In 2015, California passed major legislation to increase the state’s voter rolls by simplifying the voter registration process. Under the New Motor Voter Act, the Department of Motor Vehicles (DMV) will electronically transmit information about DMV customers who are eligible to vote to the California Secretary of State, which will add eligible customers to the voter rolls unless they opt out.

We find that this law has the potential to significantly alter the demographic composition of the California electorate, making the population of registered voters more representative of the state as a whole. Our estimates also suggest that the new system may rapidly expand the voter rolls, adding more than 2 million new registrants in the first year.

Key implementation issues will decide the impact of the New Motor Voter Act. To ensure the law’s success, the state should require DMV customers to attest to their eligibility to vote as a precondition for completing their transaction. It will also be necessary to mobilize new registrants aggressively if they are to become new voters.

Improving College Graduation Rates: A Closer Look at California State University

By Kevin Cook, Jacob Jackson

Low college graduation rates come at a high cost—lower salaries, lower tax revenue, and fewer college graduates in the workforce. At California State University (CSU), the nation's largest university system, graduation rates have an outsized financial and economic impact on students and the state.

CSU has made strides in improving graduation rates, but there is more work to be done. The system continues to struggle with graduation gaps—underrepresented students are much less likely to complete their degree compared to their peers, and these gaps have not narrowed over time. Also, CSU's on-time (four-year) graduation rates still lag behind those of similar universities nationwide.

By 2025, CSU aims to further increase graduation rates while cutting graduation gaps in half. To assist campus planning for this goal, we identify several promising programs and policies. More broadly, the CSU Chancellor's Office must work with campuses to evaluate and expand successful efforts, and the state must play a role in supporting new policies to move the needle on graduation gaps and on-time graduation.

What If California’s Drought Continues?

By Ellen Hanak, Jay Lund, Jeffrey Mount, Peter Moyle ...

California is in the fourth year of a severe, hot drought—the kind that is increasingly likely as the climate warms. Although no sector has been untouched, impacts so far have varied greatly, reflecting different levels of drought preparedness. Urban areas are in the best shape, thanks to sustained investments in diversified water portfolios and conservation. Farmers are more vulnerable, but they are also adapting. The greatest vulnerabilities are in some low-income rural communities where wells are running dry and in California’s wetlands, rivers, and forests, where the state’s iconic biodiversity is under extreme threat. Two to three more years of drought will increase challenges in all areas and require continued—and likely increasingly difficult—adaptations. Emergency programs will need to be significantly expanded to get drinking water to rural residents and to prevent major losses of waterbirds and extinctions of numerous native fish species, including most salmon runs. California also needs to start a longer-term effort to build drought resilience in the most vulnerable areas.

Pretrial Detention and Jail Capacity in California

By Sonya Tafoya

California’s persistently overcrowded jails are facing additional challenges now that public safety realignment has shifted many lower-level offenders from state prisons to county supervision. Jail capacity challenges are prompting a reconsideration of California’s heavy reliance on holding unsentenced defendants in jail pending trial—known as pretrial detention. The legal rationale for pretrial detention is to ensure court appearances and preserve public safety. But California’s high rates of pretrial detention have not been associated with lower rates of failure to appear or lower levels of felony rearrests. This report concludes that pretrial services programs—if properly implemented and embraced by the courts, probation, and the jails—could address jail overcrowding and improve the efficiency, equitability, and transparency of pretrial release decision making.
