    Arizona, Illinois, Texas

Setting

The study was conducted in 22 elementary schools in seven school districts across Texas, Illinois, and Arizona.

Study sample

A total of 142 first-grade students were included in the study (73 in the intervention group and 69 in the comparison group). Students were eligible for participation because their home language was Spanish and they were among the lowest scoring 25% of students in their schools as determined by their score on a Spanish language diagnostic tool used to assess students’ literacy skills, the Instrumento de Observación. All students were English learners. Forty-five percent of students in the sample were female and almost all were Hispanic or Latino (99%). Eighty-two percent of students were eligible for free or reduced-price meal programs.

Intervention Group

Descubriendo la Lectura (DLL) is a one-on-one tutoring intervention implemented in Spanish by trained teachers. The goal of DLL is to improve the literacy skills of Spanish-speaking struggling readers. The intervention is implemented for 30 minutes each day and uses a highly structured set of activities for each lesson, including time spent on phonics. Students progress through the intervention at their own pace, which takes between 12 and 20 weeks.

Comparison Group

The comparison condition was business-as-usual for students in their schools.

Support for implementation

DLL teachers are supported through postgraduate training, mentoring from teacher leaders or DLL developers, and a minimum of six professional development sessions each year. DLL teachers monitor DLL students' progress daily and communicate with the classroom teacher to discuss students' progress and coordinate reading strategies.
