After application submission, candidates deemed qualified must complete all subsequent steps to advance in this selection process, which includes the following:

Minimum Qualification Supplemental Questionnaire (MQSQ): Candidates will be required to complete a MQSQ as part of the employment application. This MQSQ is designed to obtain specific information regarding an applicant's experience in relation to the Minimum Qualifications (MQ) for this position. The MQSQ will be used to evaluate if the applicant possesses the required minimum qualifications. 

Basic Supervisory Exam (BSE) Weighted 60%: Candidates will be administered a written multiple-choice examination that is designed to measure basic knowledge of various supervisory practices and procedures (e.g. directing, counseling, guiding, evaluating, motivating, disciplining, developing and training subordinates, delegation, etc.) as well as customer service and reading comprehension.

The score you achieve on this examination shall be valid and 'banked' for three years, starting from the date of the examination. This test is used for other supervisory 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 test for this future announcement is held within one year of the date of this examination, your score will be automatically applied to that announcement. After one year, you have the option to either apply your test score to the other announcement or re-take the test. Should you re-test, your re-test score would become your official score since it is the most recent.

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 on the BSE to continue in the selection process. 

Training & Experience (T&E) Evaluation Weighted 40%: Candidates who pass the BSE will receive a Supplemental Questionnaire via email.  Candidates will be evaluated on their relative knowledge, skill and ability levels in job-related areas.

Candidates must achieve a passing score on all exam components listed above in order to be placed on the eligible list/score report.

The San Francisco Municipal Transportation Agency (SFMTA) has determined that Class 7244 Power System Supervisor I is a “safety-sensitive” position, per regulations issued by the Federal Transit Administration (49 CFR Part 655). Federal law requires that all transit employees who perform safety-sensitive functions be subject to random, post-accident, reasonable suspicion, return-to-duty and follow-up drug and alcohol testing. All applicants for Safety-Sensitive positions shall undergo urine drug testing prior to employment and within 90 days prior to performing Safety-Sensitive functions for the first time. Receipt by the SFMTA of a negative test result is required prior to the employee being placed on the payroll. A positive, adulterated, negative dilute or substituted test will result in a decision not to hire, and the applicant’s name will be removed from the list of eligibles for Safety-Sensitive positions. The SFMTA will not consider hiring any person who tested positive, adulterated, substituted or refused to submit to testing for a minimum of two years following the positive test.

Each applicant who has worked for a Department of Transportation (DOT) – regulated employer within the last two years will be required to sign a consent form, prior to appointment, authorizing SFMTA to obtain information from their prior employers concerning their drug and alcohol test history. Each applicant will also be required to provide SFMTA with information regarding whether, during the last two years, the applicant tested positive or refused to test on any pre-employment drug or alcohol test administered by an employer to which the applicant applied for, but did not obtain, safety-sensitive transportation work covered by DOT drug and alcohol testing rules. SFMTA will not hire any applicant for a safety-sensitive position who fails to provide this information or fails to provide written consent for the release of information from prior employers.
