For the autoscored Leadership Challenges Series, stability was assessed with test-retest administration. 104 people took the simulation twice, with the mean interval of 35 days. Coefficient was 0.51.

When the criterion is measured at the same time as the construct, criterion validity is referred to as concurrent validity. Concurrent validity is the degree to which the scores on a test are related to the scores on another, already established test, administered at the same time. However, other criteria can also be used.

Intercorrelations between the Leadership Challenges Series and an established RolePlay, were found to be significantly related. Adaptive Leadership was found to be significantly correlated with all the aspects measured by the Role Play such as Building Talent, Creating Collaborative Partnerships, Drive for Excellence and Innovating thinking. This pattern may reflect the relatively stronger relationship Adaptive Leadership has with responding to the people-related challenges posed during the role-play. Coefficients ranged from 0.31 to 0.72

By collecting test scores and criterion scores (e.g. job performance ratings, grades in a training course, supervisor or manager ratings), one can determine how much confidence may be placed in using test scores to predict job success. In such cases, criterion validity is referred to as predictive validity. In the business domain, using a validation sample of 235 candidates, it was reported that the overall composite scores on Leadership Challenges Series correlated .32 with panel interview ratings and .28 with performance ratings by the internal stakeholders.

Jombay Assessments have defined a global set of norms that include all data across industries, functions, and experience levels. For each assessment, Industry-Function-Experience level combinations are derived for norms with significant population data. Norming has been done at the trait level and is based on the mean and standard deviation for each sample. A data of at least 100 respondents per combination is considered as a significant population for generating norms. Norms are defined by taking the mean and the standard deviation of the sample's scores and dividing the sample into 6 buckets. Jombay norm data is annually updated.

Jombay is committed to ensuring that its tests are of the highest quality and rigor and developed to be unbiased and culture fair. All items in this assessment use simple language that is easily understandable, are gender neutral, and are comprehensively evaluated during the development process.

Jombay ensures that its products are not offensive or controversial, do not reinforce stereotypical views of any group, are free of racial, ethnic, gender, socioeconomic, or other forms of bias, and are free of content believed to be inappropriate or derogatory towards any group.
