Selection Plan

Minimum Qualification Supplemental Questionnaire (Weight Qualifying):
Candidates will be prompted to complete a Supplemental Questionnaire as part of the online employment application. This Minimum Qualification Supplemental Questionnaire is designed to obtain specific information regarding an applicant's experience in relation to the Minimum Qualifications for this position. Applicants must also complete the official application. It is essential that applicants provide complete information in identifying their education, experience and training. The Minimum Qualification Supplemental Questionnaire will be used to evaluate if the applicant possesses the required minimum qualifications.

Written Examination (Weight 100%):
Candidates deemed to meet the minimum qualifications will be invited to participate in a written multiple-choice examination designed to measure their relative knowledge, skills and abilities in job-related areas, which may include, but are not limited to: knowledge of trench excavation practices and sewer maintenance and repair including methods and tools as required by OSHA standards; knowledge of the skill and ability to use a variety of tools and equipment required in the construction, maintenance and repair of a municipal sewage system; ability/skill to operate power devices such as air compressors, winches, pavement breakers and trash pumps; ability/skill to communicate clearly in writing; ability/skill to communicate verbally including operating a two-way radio or cell phone; ability to follow oral and written instructions accurately; ability to lead and direct a sewer repair crew; ability to perform mathematical calculations necessary to estimate quantity and costs of materials and work hours needed for a project. A passing score must be achieved on the written exam in order to continue in the selection process. This is a standardized examination, and, therefore, test questions and test answers are not available for public inspection or review.

Any scores attained on the written examination component 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 any test components for which you have already attained a score. If the selection process for the future announcement is held within one year of the date of this examination and it includes this written examination component, your score for the corresponding test component 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 test component. 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 test component 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 certification rule for the eligible list resulting from this examination will be Rule of Five Scores. Additional selection processes may be conducted by the hiring department prior to making final hiring decisions.

Eligible List/Score Report:
A confidential eligible list of applicant names that have passed the civil service examination process will be created, and used for certification purposes only. An examination score report will be established, so applicants can view the ranks, final scores and number of eligible candidates. Applicant information, including names of applicants on the eligible list, shall not be made public unless required by law. However, an eligible list shall be made available for public inspection, upon request, once the eligible list is exhausted or expired and referrals resolved. The eligible list/score report resulting from this civil service examination process 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 12 months, and may be extended with the approval of the Human Resources Director.

Upon approval of the Human Resources Director (see Civil Service Rule 111A.26.5), the eligible list/score report resulting from this announcement may be used by other departments that also use this classification or a similar classification. To find other Departments which use this classification, please see https://sfdhr.org/sites/default/files/documents/Forms-Documents/Position-Count-by-Job-Codes.pdf.

Medical Examination:
Prior to appointment, candidates must successfully pass a medical examination to determine their ability to perform the essential functions of the job and/or the ability to meet the physical minimum requirements.

Drug Testing Requirement:
Applicants for positions in this classification who are not currently employed by the City and County of San Francisco in a safety-sensitive position represented by the Laborers’ International Union, Local 261 are required to pass pre-employment drug and alcohol testing. All employees in this classification may also be subject to drug and alcohol testing upon reasonable suspicion or after a work-related accident. Applicants with a positive result from a pre-employment drug test will be restricted from hire in safety-sensitive positions for six months after the date of the positive test.

Conviction History

As a selected candidate 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 selected candidate. 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 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 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 a selected candidate, the hiring department will contact you to schedule a fingerprinting appointment.
