2. Preliminary Questionnaire (Qualifying) - During the application process, candidates will be prompted to complete a Preliminary Questionnaire as part of the online employment process. Please answer the Preliminary Questionnaire carefully and thoroughly. The purpose of the Application and Preliminary Questionnaire is to obtain specific information regarding an applicant's education, experience, and training in relation to the Minimum Qualifications for this position.

To see a list of the knowledge, skills, and abilities being tested, click here. 

This is a standardized examination and, therefore, test questions and test answers are not available for public inspection or review.

A passing score must be achieved to be placed on the eligible list/score report. The hiring department may administer additional position-specific selection procedures to make final hiring decisions.

The score that you achieve on the examination will be valid and "banked" for three years, starting from the date of the examination. This means that for the next three years, you will not be required to take this test again should you apply and be found eligible for a future announcement for which this particular test is used. If the test for this future announcement is held within 12 months of the date of this examination, your score will be automatically applied to that announcement.

Re-testing is permitted no sooner than twelve months from the date of the examination and only in association with your eligibility for another announcement for which this test is used. Please note that, should you re-test, your re-test score would become your official score going forward since it is the most recent score (even if it turns out to be lower than your original score).

Candidate scores on this examination may also be applied to other announcements involving other job titles, when directed by the Human Resources Director.
