LPI is committed to providing the IT community with exams of the highest quality, relevance, and accuracy. This commitment requires that our exam development process is highly detailed, time consuming, participatory, consultative and employs many of the proven techniques used by most other IT certification programs.
LPI exams are created using psychometric techniques, which results in exams which are of high quality and relevance to the skills being tested. Psychometrics, the scientific study of testing and measuring mental capacity, is used throughout LPI certification development to ensure that our exams reflect the needs of the IT community and industry.
The challenging issue is that anyone could come up with a list of tasks that they believe a Linux professional should be able to do. As a result, if you ask ten different Linux professionals what a “junior-level” IT professional should do, you may receive ten different sets of answers. Who is to say which list is more correct?
The third major stage of development is to use the results from the Job Analysis Study to develop the actual objectives for the exam(s). Objectives express specific things that Linux professionals must be able to do. Each objective is assigned a weighting value indicating its importance relative to other objectives.
With the objectives finalized, the next stage is to write the questions that will appear on the exams (note that within the world of exam development, a question is referred to as an item).
After all of the items have been collected and reviewed, the next stage of development is to actually assemble the items into exams and deploy the exams globally.
