Innovation delivers greater insight

TerraNova® Common Core features item types that go beyond traditional multiple-choice tests. On the same scale and all in the same test book, the test includes:

  • Integrated Performance Tasks (PT)
  • Constructed-Response (CR) items
  • Extended Constructed-Response (ECR) items
  • Multiple-Choice

Using one test educators can compare student results on national and common core standards across grades and ability levels. All items have been developed and field-tested offering the most reliable and valid measure of any national achievement test in the market. TerraNova Common Core covers reading, English language arts, and mathematics for Grades 3–8.

A New Era in Assessment Begins Now

TerraNova Common Core breaks the limitations of a multiple-choice test by offering unique item types such as CR, ECR, and PT items. No other national achievement test offers this combination of items all on the same scale, all in one test book.

TerraNova Common Core Addresses Assessment Priorities

The Smarter Balanced Assessment Consortium (SBAC) has issued important guidelines for CCSS assessments. These include:

  • Inclusion of new item types: Short Constructed-Response*, Extended Constructed-Response*, and Performance Tasks*
  • Data to show current achievement and growth
  • State to state comparability
  • Tests can be deployed twice annually

TerraNova Common Core addresses each of these guidelines making it an optimum choice for use now as states and districts transition to the CCSS.
