The ERB is the ACCS recommended standardized test for grades 2-10.
As the Common Core absorbs or eliminates other tests like the Stanford Achievement and the TeraNova, we advise schools move to the ERB. There is a membership fee with the ERB, plus testing expenses. This can tend to increase the cost. The ACCS is working to bring more value to members using this testing data (comparison tools with other ACCS schools, etc.). We hope this value will help offset the higher costs.
Please see ERB-CTB-4 in Student Services for recommendations, school test data, and more.
