Thornton High School's dropout rate in the 2019-20 school year increased by 23.5% compared to the previous school year’s dropout rate of 14.9%, according to the California Department of Education (CDE).

CDE data of graduation and dropout rates confirms there is a growing achievement gap between Latino, Black, and English learner students. The achievement gap refers to the disparities in academic performance associated with race and class.

According to data provided by the National Center for Education Statistics in 2018, of the 48 states where data was collected, Black males remain at the bottom of four-year high school graduation rates.

Closing the achievement gap earlier in the schooling process, such as during elementary school, can improve high school graduation rates and decrease dropout rates. Individually tailored student support is one way that is proposed to accomplish this.

In The Long-Term Impact of Systemic Student Support in Elementary School: Reducing High School Dropout, Terrence J. Lee-St. John, a Biostatistician at the Research Department of Cleveland Clinic Abu Dhabi, says, “Students often fail to complete high school for complex reasons that often manifest long before they reach high school. Individually tailored student support during elementary school can lead to lasting and meaningful effects.”
