TRC Atlas Spanish

The TRC Atlas Spanish texts have been revised with authentic text to improve your students’ reading experience. These changes have been made based on feedback from the LAUSD Multilingual & Multicultural Education Department (MMED), dual- language schools, and Spanish literacy authors and experts, including Elizabeth Jimenez and Gisela O’Brien. Syntax, vocabulary, and cohesion of the texts have been enhanced to be more appropriate for Spanish language readers.

Indicadores Dinámicos del Éxito en la Lectura (IDEL) is a research-based formative assessment series of measures designed to assess the basic early literacy skills of children learning to read in Spanish.

As part of our commitment to continuous improvement, we are happy to announce that we will add the Instruction page to reporting for Spanish mCLASS assessments on September 1. mCLASS Instruction consolidates all the instructional resources available for a student on a single page. With mCLASS Instruction, educators can: 

  • View each student’s observed skill gaps and related activities from Item-Level Advisor
  • Access student-specific resources based on assessment results and observed patterns
  • View the student’s small group assignment and recommended group activities
