Sweetwater Union High School District — Case Study

Sweetwater Union High School District in Chula Vista, California implements LAS Links® in its English Language Development (ELD) courses to measure English learners’ (ELs) progress and inform instructional decisions.

Using the integrated suite of English language proficiency assessments from DRC|CTB, the district reports improved student performance across all language domains and ELD levels.

In addition, in 2010, the EL subgroup at every middle and high school achieved at least double its Academic Performance Index (API) target, surpassing state averages and the performance of comparable school districts in San Diego County.

Filling in the Achievement Gaps for English Language Learners

A strategic and accurate decision-making plan is vital to filling in the achievement gaps for English language learners. To begin this planning process, educators need an English language proficiency assessment that pays special attention to the following:

  • Identification and Placement
  • Tracking Progress
  • Curriculum Planning
  • Program Entry/Exit

Identification and Placement
Accurate placement promotes quality instruction and helps students make progress rapidly. LAS Links evaluates students in listening, speaking, reading, and writing to accurately and reliably place them within the program that best meets their needs.

Tracking Progress
Benchmark Assessments provide information that helps teachers monitor students' progress toward achieving state English language proficiency standards. This feedback enables teachers to measure and report progress throughout the year to adjust the curriculum and target student learning.

Curriculum Planning
Once students have been identified at their appropriate level of English proficiency, teachers can augment instruction by using the lesson plans contained in the Instructional Guidance materials. These lessons are organized by content area and proficiency level, allowing ELL students to have success in academic subjects.

Program Entry/Exit
Enables accurate identification and placement of ELL's and annual evaluation of ELL students. Additionally, LAS Links can help determine whether students are ready to exit programs.

English Language Development Model Using LAS Links

DRC|CTB provides high quality assessments for grades Pre-K–12, and has been involved in language proficiency for more than 30 years beginning with the development of the Language Assessment Scales (LAS®). LAS Links is based on the tenet that second-language acquisition occurs when students have multiple opportunities to process meaning with their fellow students, teachers, and other adults in the school and elsewhere. Students process information best when that information is systematically introduced, when it is engaging, and when it is accompanied by opportunities to practice the knowledge and skills required to learn the English they will need for academic, social, and test situations.

In creating the LAS Links family of assessments, DRC|CTB applied years of second language acquisition research. This research is reflected in the types of items, topics, language usage, linguistic expectations, and scoring that are utilized in these assessments. Careful consideration has been given to distinguish the content of LAS Links English language proficiency development from that included on English language arts achievement tests.

Throughout the lifecycle of a student's acquisition of English as a second language, from beginner to fluent, LAS Links provides a measure of growth that reflects the different rates of growth evident in the ELL population.

Helping Mainstream Teachers Become More Effective in Meeting the Needs of All Their ELL Students

With classrooms more diverse than ever before, teachers throughout the country are facing new challenges—rapidly changing demographics colliding with federal civil rights requirements, politically charged debates on bilingual education, and limited school resources. Under federal law all English language learners (ELL) have the right to appropriate language support services until they achieve English proficiency. The most recent confusion seems to be on how to apply federal civil rights laws to the education of ELL students.

Districts can meet this federal obligation by tracking the educational progress of each student to help accelerate their English language development. LAS Links helps teachers develop appropriate lessons and instructional strategies to target students’ language needs.

For a minimal cost, schools across the country can better serve their ELL students with LAS Links. Now is the time to provide teachers with the immediate access to lesson plans that can be used to accelerate students' English language development and enable them to become more successful in academic classrooms.
