The Process: Job Task Analysis

After development of a program structure and a job description for an exam or series, the next stage is to scientifically determine the skills, tasks and areas of knowledge needed for the job.

The challenge: Anyone could come up with a list of tasks they think a Linux professional should be able to do. If you ask 10 Linux professionals what a “junior-level” professional should do, you might get 10 lists. Which list is correct?

Our solution: We ask a large number of Linux professionals for their lists of necessary job duties, and then compile the responses to find the common and most important tasks. The most important tasks show up on all lists.

This process is called job analysis study or job task analysis. LPI has completed extensive job analysis surveys of Linux professionals to help ensure exams are unbiased and constructed fairly.

How We Do It:


First we work with a large pool of subject-matter experts to compile an exhaustive list of all the tasks that they think might be performed by the target audience of the certification.

Job Analysis Survey

Next, the tasks collected during the pre-survey go into a job analysis survey. This survey asks practicing Linux professionals to rate each task in several ways:

  • Frequency: How often they perform the task.
  • Importance: How important it is for an administrator to be able to perform the task.

Data analysis

Finally, we conduct statistical analysis of the survey responses. We compute statistics indicating, on average, how critical respondents rated each task. This analysis guides the determination of the final job task list.
