To succeed in the 21st century, all students need to perform to high standards and acquire mastery of rigorous core subject material. Alignments to rigorous curriculum frameworks and correlations to commonly used assessments help us focus teaching and learning systems around the right college and career-ready outcomes for all students.

Strongly Correlated to Commonly Used Assessments

Lexia’s Assessment Without Testing technology gathers norm-referenced student performance data without stopping to administer a test. 

Predictor scores and Benchmark status from Core5 were strongly correlated with scores from commonly used assessments. On Target Predictor scores were used to predict proficiency on the  STARMAPDIBELS Next, and AIMSweb assessments with more than 80% accuracy. These findings indicate that Core5 can serve not only as an instruction program but as a key component in a school's literacy assessment.
