IDEL 7th Edition Materials

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.

The IDEL measures are not a translation of the DIBELS measures. They take into account the linguistic structure of the Spanish language including the phonology, orthography, and syntax. Like DIBELS, the IDEL measures are based on the same theoretical and evidence-based principles of how children learn to read in alphabetic languages such as English and Spanish.
