The Illinois Early Learning Standards assesses skills and academic achievements for various age groups according to normative measures for specific age groups. The purpose is to monitor progress, deficiencies and assist in setting goals for IEP’s (Individualized Education Program).

Scores regarding the relationship of the PEAK Training System was significant (p=0.000) and correlated strongly with the standard PPVT scores (r=0.908)” (Dixon, Carmen, et al, 2014, p. 611). The relationship between PEAK and the Standards Scores was “a mean score of 35.69 for all participants in the Illinois Early Learning Standards.

The PEAK assessment program has been well documented to provide an extensive insight to persons with developmental delays and skill deficits. Not only does the assessment distinguish deficiency it provides instructional programs to correspond with inadequacies in development. I am currently applying this assessment and program with a thirteen year old male who falls in the autistic spectrum. It has revealed many ‘holes’ in his understanding of his world and the language abilities both receptive and expressive.
