Assessment Science

Assessment Science is our research-backed, state-of-the-art methodology that powers the creation of our developer skills content. Our signature approach ensures that you provide valid, reliable and fair assessments — helping you to add consistency, remove unconscious bias, and hire the right developer for the right role, every time.

Valid

Is the test job-related?

  • Questions accurately assess the knowledge areas and skills that they intend to measure
  • Questions are based on job-related, critical skills
  • We collect evidence of validation for all assessments

Reliable

Is the test consistent?

  • We test the extent to which an assessment is free from random measurement error
  • Test-retest studies result in high correlations between scores
  • Questions follow standardized scoring methodology

Fair

Is the test unbiased?

  • Assessments are objectively administered and scored
  • Fairness and sensitivity reviews remove unconscious bias regarding race, culture, religion, gender, or disability of test taker

Deeper developer skill assessment expertise

From interns to experienced hires, evaluate for any developer role by sending technical challenges and/or conducting live interviews.

Validated Content Library

We have the largest library of assessment content in the world. With 2,700+ questions spanning 95 in-demand skills, all content in our library undergoes a rigorous validation process. Our test questions are:

  • Developed by subject matter experts
  • Field-tested by IO psychologists to ensure they function as intended
  • Subject to fairness and sensitivity reviews to remove any unintended bias, including racial or ethnic bias, gender bias, socioeconomic bias, and more.
  • In compliance with EEOC and OFCCP regulations.

Standardized Scoring Methodology

We run a candidate’s code submissions against a set of test cases, which form the foundation of an automated score. While analyzing the candidate’s code, we look at factors like:

  • Is the code correct?
  • Does the code run quickly?
  • Is it efficient in its use of space?
