Understanding validity and reliability of coding assessments
Coding tests are used to establish a relationship between an applicant and the job. The validity of a test is determined by whether the skills that are being assessed in the test are related to the job requirements.
The reliability of a test is based on its dependability and consistency of assessing applicants based on specific skills. A test that yields similar scores for the same group of applicants who repeat the test is considered reliable.
Content creation and review
Our assessment content is meticulously crafted by Subject Matter Experts (SMEs) with extensive hands-on experience in their respective fields. This content then undergoes a rigorous peer-review process by a diverse pool of SMEs, further ensuring its relevance and accuracy.
Field testing by I/O psychologists
Finally, our content is field-tested by our partner Industrial-Organizational (I/O) psychologists. These professionals analyze the results to ensure valid assessment of the intended skills and identify any potential bias.
Job role to skill mapping
Our expert team, consisting of industry veterans and domain-specific specialists, meticulously maps job roles to the essential skills required for success. This ensures our assessments target the right skills for the roles you're hiring for.
Test-retest studies
We conduct comprehensive test-retest studies where individuals with relevant skills retake the assessments after a set period. High correlations between initial and subsequent scores demonstrate the stability and consistency of our assessments over time.
Built-in reliability measures
We utilize various automated features within our platform to continuously monitor and maintain test reliability, and address any potential inconsistencies in the assessment experience.
