Review by: David Geary, University of Missouri
"A much needed, scientifically grounded instrument for the assessment of early numerical abilities. The test represents a significant and welcomed advance in our ability to identify early risk for long-term difficulties in learning mathematics."
Review by: Herbert Ginsburg, Teachers College Columbia University
"Draws upon [Nancy Jordan's pioneering] research to produce a valuable measure that can be used to identify children in need of help and to plan sound interventions for them."
Review by: Nancy Krasa, co-author, Number Sense and Number Nonsense: Understanding the Challenges of Learning Math
"An indispensable, teacher-friendly tool for ensuring that all students shoot out of the starting gate when they get to first-grade math."
Review by: Sally Moomaw, University of Cincinnati
"In addition to supplying a numerical score for areas related to number sense, the screener allows the assessor to document the strategies children use for addition and subtraction. This is of particular interest to teachers, who can apply this information to their classroom instruction."
Review by: Daniel Berch, University of Virginia
"Although many intervention programs and assessment tools profess to be research-based, the Number Sense Screener (NSS) unquestionably meets the strictest standards for making such a claim. An unparalleled tool for use by classroom teachers, learning specialists, and school psychologists."
