This post details the results of a job related validity study of 90 bus drivers. The goal of the study was to identify and validate the ideal behavioral profile for the bus driver position.

The results are used to provide a behavioral benchmark to compare new applicants against, to help identify the best possible candidates for the role.

Job Title: Bus Driver

Job Description:

The client company is municipal transit authority in a large metropolitan city. This statistical analysis is based upon Predictive Index Patterns and performance information supplied by the client company for 90 drivers. Each bus driver is responsible for picking up and discharging riders along a fixed route, as well as providing riders with timely and courteous service.

Study Objectives:

The objectives of this analysis of the Predictive Index patterns of Bus Drivers are:

  1. To determine the Factors (personality traits or constructs) measured by the Predictive Index that relate most significantly to higher and lower levels of performance in the job. (Complete definitions of the Factors are contained in the Predictive Index Management Workshop Notebook. Due to the complexity of that material and the fact that this analysis has been prepared for individuals who have attended that Workshop, the complete construct definitions will not be included in this report.)
  2. To develop evidence of the validity of the Predictive Index in this job classification using the criterion-related validation procedures (evidence of work relatedness) prescribed for this purpose by the Equal Employment Opportunity Commission (EEOC) Guidelines. This study has achieved these objectives. Many of the statistical relationships between performance and the Predictive Index Factors and Factor Combinations are particularly strong and meet or exceed the EEOC requirements for determination of criterion-related validity (work relatedness). The findings, recommendations, and statistical information are reported below.

Company Information and Performance Data:

The client company is municipal transit authority in a large metropolitan city. This statistical analysis is based upon Predictive Index Patterns and performance information supplied by the client company for 90 drivers.

Each bus driver is responsible for picking up and discharging riders along a fixed route, as well as providing riders with timely and courteous service.

The job performance of each Bus Driver was assessed with the following six criteria:

  1. Tenure Number of years in the position.
  2. Accidents The average number of chargeable accidents a driver had per year.
  3. Absenteeism Total percent of days a driver was absent per year.
  4. Commendations Average number of positive customer comments a driver received per year.
  5. Complaints Average number of negative customer comments a driver received per year.
  6. Infractions Average number of miscellaneous departmental disciplinary infractions (e.g. using a cell phone while driving) a driver received per year.

The data was collected and analyzed for statistically significant correlations. Full Study findings are available upon request. For the purposes of this post I am going to provide the summary of the results and key takeaways.\
