Selection Procedures

Supplemental Application: Applicants are required to complete a Supplemental Application as part of the application process. The purpose of the Supplemental Application is to obtain specific information regarding an applicant's experience in relation to the Minimum Qualifications for this position. It is essential that an applicant provide complete information in identifying and describing their experience. The Supplemental Application will be used with the official application form to evaluate if an applicant meets the minimum qualifications.

This is a standardized examination and, therefore, test questions and answers are not available for public inspection or review. Scores attained on the Sewage Plant Stationary Engineer Written Examination will be valid and 'banked' for three years, starting from the date of the examination. This means that, during this three-year time period, you will not be required to take the Sewage Plant Stationary Written Examination.

The Sewage Plant Stationary Engineer Written Examination may be used for other classes; therefore your test score may be applied to one or more of these classes if you choose to apply to future recruitments. If the selection process for the future announcement is held within one year of the date of this examination and it includes the Written Examination, your score will be automatically applied to that announcement. However, after one year, you have the option to either (a) apply your test score to the other announcement or (b) re-take the Sewage Plant Stationary Engineer. Re-testing is permitted no sooner than one year from the date of the examination and only in association with your eligibility for another announcement for which the Sewage Plant Stationary Engineer Written Examination is used. Please note that, should you re-test, your re-test score would become your official score since it is the most recent. The department may administer additional selection procedures to make final hiring decisions.

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

Qualified candidates will be notified of the exact date, time and location of the examination.

CERTIFICATION RULE: The certification rule for the ranked eligible list resulting from this examination will be Rule of Ten Scores.

ELIGIBLE LIST: The eligible list resulting from this examination is subject to change after adoption (e.g., as a result of appeals), as directed by the Human Resources Director or the Civil Service Commission.
The duration of the eligible list resulting from this examination process will be 6 months, and may be extended with the approval of the Human Resources Director.

Conviction History

As a finalist for a job, you will be fingerprinted, and your fingerprints will be sent to the California Department of Justice (DOJ) and the Federal Bureau of Investigation (FBI). The resulting report of your conviction history (if any) will be used to determine whether the nature of your conviction (or arrest, in limited circumstances) conflicts with the specific duties and responsibilities of the job for which you are a finalist. If a conflict exists, you will be asked to present any evidence of rehabilitation that may mitigate the conflict, except when federal or state regulations bar employment in specific circumstances, such as:

  • Candidates applying for positions with the Unified School District and the Community College District may be disqualified from consideration should their conviction history not meet the standards established under the California Education Code.
  • Candidates applying for positions with the Recreation and Park Department may be disqualified from consideration should their conviction history not meet the standards established under California Public Resources Code 5164.

Having a conviction history does not automatically preclude you from a job with the City.

If you are selected as a finalist, the hiring department will contact you to schedule a fingerprinting appointment.
