Definition: Percentage of all public school students tested in 3rd grade who scored proficient or advanced on the English Language Arts California Standards Test (e.g., 44% of 3rd grade students in California scored proficient or advanced in 2010).

Footnote: Years presented are the final year of a school year (e.g., 2009-2010 is shown as 2010). LNE (Low Number Event) refers to data that have been suppressed because there were fewer than 20 estimated students with proficient or advanced scores. N/A means that data are not available. Data are not shown for schools operated by county offices of education because of missing data.

Measures of Reading Proficiency on Kidsdata.org

On kidsdata.org, reading proficiency is measured by the percentage of 3rd graders in public schools who score proficient or higher on the English Language Arts California Standards Test (CST). These data are available by English fluency, race/ethnicity, and socioeconomic status.

In order to score proficient on the CST, a student must demonstrate a competent and adequate understanding of the knowledge and skills measured by this assessment, at this grade, in this content area; scoring advanced requires a comprehensive and complex understanding.

Why This Topic Is Important

Third grade reading scores are highly correlated with later academic success; some research indicates that reading proficiency at the end of third grade is predictive of whether or not a student will graduate from high school. By the end of third grade, children should show evidence of reading comprehension and be able to read unfamiliar words by employing various strategies, such as roots, prefixes, and suffixes. Early intervention is critical for children who are struggling with reading. Third grade marks the transition from instruction in reading to relying on students' reading skills to teach subject material -- moving from "learning to read" to "reading to learn" (1).

Policy Implications

Despite broad agreement on the need to boost reading proficiency among California students and to bridge the racial/ethnic achievement gap, there is sharp disagreement on policy reforms to achieve these goals. Research has documented the key domains for reading improvement (e.g. understanding the sounds words make, fluency in reading, vocabulary, etc.), but there is no single set of evidence-based approaches for making improvements in those domains. Quality teaching, however, is one key point of consensus. Teacher quality has been shown to have a significant impact on student achievement (1, 2, 3). As California and other states implement new “Common Core” state standards in English-language arts and math over the next several years, policymakers also will face challenges in authorizing new assessments, curricula, and teacher evaluation systems that align with the standards (4).

According to research and subject experts, policy options that could improve reading proficiency include:

  • Improving teacher quality at every grade level (1, 2, 3); recognizing that acquiring reading proficiency by third grade is a key indicator of later school achievement (5)
  • Investing in quality preschool for California children, to promote kindergarten readiness and lay the foundation for later achievement (6)
  • Choosing carefully before investing in reading interventions, given the developing research base and mixed results of many programs (7); key elements in successful literacy initiatives include ongoing student assessments as well as teacher professional development (8)
  • Articulating state, district, and school-level middle school policies emphasizing improving academic outcomes for all students, including tying student outcomes to teacher evaluations; aligning middle school curricula, instructional practices and assessments with state standards; and prioritizing student academic performance when selecting superintendents and principals (9)
  • Analyzing district and school-level data on student achievement and progress by racial/ethnic group, especially for children of color, so that data can inform policy (10)
  • Encouraging and investing in comprehensive, evidence-based policies to promote family involvement in school, as it is strongly related to children’s academic achievement (11). Family involvement should be integrated as part of the school instructional strategy, and family engagement policies should be evaluated for effectiveness.

How Children Are Faring

The percentage of 3rd graders scoring proficient or higher in English Language Arts on the California Standards Test (CST) increased between 2003 and 2010 statewide and in the most populous counties. Specifically, in 2010, 44% of California 3rd graders were proficient in English Language Arts, compared to 33% in 2003. Reading proficiency in 3rd grade varies by region, English fluency, race/ethnicity, and socioeconomic status. However, the percentage of California 3rd graders demonstrating reading proficiency rose among English Learners, economically disadvantaged students, and students in all racial/ethnic groups for which data are available between 2005 and 2010.
