The Revised Implicit Theories of Intelligence Scale (RITIS)


The RITIS assesses students implicit beliefs that with effort a person can grow and become smarter (mindset).


The RITIS is commonly administered across wide ranges of ages and contexts.

Typical Performance

We are establishing the typical performance for college students. This will be updated once we have additional data.

Example question

I don’t think I personally can do much to increase my intelligence.

  1. Strongly agree

  2. Agree

  3. Neutral

  4. Disagree

  5. Strongly disagree


The RITIS is an adaptation of prior mindset assessments. The RITIS has been used by many populations but was originally validated with high school students.
