What do these ratings mean?

NCRTI and NCII are both dedicated to helping students who may need additional support succeed. Many wonderful products are rated highly for their efforts toward this cause. At times, some companies may even be a bit overzealous in their celebration, claiming that they have the “highest” ratings overall. In the spirit of honest communication, let’s examine these ratings closely.

How do NCRTI ratings work?

NCRTI rates educational assessments for screening. Their system spans these evidence ratings:

  • Convincing evidence
  • Partially convincing evidence
  • Unconvincing evidence
  • Data unavailable or inadequate

Renaissance Star Reading, Star Math, and Star Early Literacy have met NCRTI’s criteria for evaluating the scientific rigor and are highly rated as screening tools.

How do NCII ratings work?

NCII rates educational tools for progress monitoring. Their system spans the same evidence ratings:

  • Convincing evidence
  • Partially convincing evidence
  • Unconvincing evidence
  • Data unavailable or inadequate

Renaissance Star Reading, Star Math, and Star Early Literacy have met NCII’s criteria for evaluating the scientific rigor and are highly rated as progress monitoring tools for measuring general outcome measures. Renaissance Accelerated Math and MathFacts in a Flash are highly rated as progress monitoring tools for mastery measure.

Did you know?

NCRTI and NCII ratings do not compare products with other products, and ratings do not serve as an endorsement of a particular product. This means that, tempting as it is to say, according to NCRTI and NCII guidelines, it’s not accurate to describe a product as “highest rated” in comparison to other products.
