Applying for a Job

  • Applications are accepted for County examinations only when the bulletin is posted which announces that the examination is open and applications are being accepted.
  • Please follow the filing instructions as outlined on the job bulletin. Applicants must submit applications specifically how and/or where the bulletin states the application should be filed.
  • Examinations usually have deadline dates by which application must be submitted. This means that the applications must be received in the designated location by the closing date; otherwise, the application will be rejected as late. A postmark by the closing date is not sufficient.
  • Any false statements of material facts or omissions may subject the applicant to disqualification or dismissal.

Online Job Application

This is the quickest and most efficient method of applying for County jobs. We encourage you to complete an online application because:
  • You only have to complete one profile. Your profile will be retained in the County's database and you may use the same profile to apply for several jobs that match your experience and education.
  • If you apply online, and you include an email address, you will receive immediate notification that your application has been received. If you don't have an email address you can obtain one free through online services (Yahoo, MSN,, or GMail).
  • If you don't have a computer and would like to apply online, you may visit one of the many locations where computers are available including your local library. If you wish, you may still choose to complete a paper application and mail to address listed on the job bulletin.

How to Apply

We understand that applying for a job in government service can be a complicated process. The following is a brief overview about how you can successfully submit your application.

Start by Reviewing the Official Job Announcement (also called the Bulletin)

  • Requirements
    • Minimum/Selection Requirements are not negotiable
    • If you are sure you do not meet the requirements keep searching for an examination for which you qualify
  • Type of Recruitment
    • If this examination is only open to employees of the County of Los Angeles or it is for a specific group, i.e., veterans, student workers, internship participants, etc., please make sure you meet the criteria before applying
  • Open Examination Only
    • If the close date of the examination is not listed on the job announcement, call the contact number on the bulletin to make sure the examination is still open
    • Examinations are subject to close without notice
  • Special Requirement Information
    • Include all proof of education, licenses and supplemental information as requested. If you do not do this, your application may be rejected

  • Examination content
    • If the examination has a written test, you may want to practice your skills before taking the test
  • Application and Filing Instructions
    • Sometimes examinations have special instructions, like 'online filing only' or 'supplemental application must be attached'
    • If you do not follow the posted instructions, this may cause your application to be rejected

Fill out your application completely

  • You must provide all the information requested to assure that the Department will be able to assess your qualifications
    • Beginning with your most recent experience, please account for all employment and any periods of unemployment
    • Include self-employment, military service, and volunteer work related to the job for which you are applying

    • County experience is based on a 40 hour work week. Part time experience will be prorated.
    • For example, 12 months of experience working 20 hours per week, is calculated to be 6 months of qualifying experience
  • Throughout the application, focus on accomplishments that relate most closely to the job you want
    • Use the job announcement as a guide
    • Caution: Do not copy the job announcement word-for-word; this may result in application rejection

  • Resumes are not substitutes for filing out the application
    • Attaching a resume is a great opportunity to provide detail about your work experience

    • Conflicting information may cause the examination analyst to question the authenticity of the information you provide

Apply on Time

  • If the examination you are interested in does not have a posted close of filing, call the departmental number listed on the bulletin to assure you meet the close of filing deadline
  • This information is usually found at the bottom of the last page of the bulletin (if you are viewing or printing from DHR website)
  • Do not wait until the last minute to apply
    • Applying at the last minute can cause you to make mistakes that cannot be fixed
    • If you are applying online, you will want to make sure your computer is compliant with Los Angeles County's browser requirements
    • A large number of applicants trying to send information electronically at 5:29 p.m. on the last day of filing may cause computer issues


  • Computer glitch errors: contact the department immediately
    • Document any computer related complaints
    • Without documentation, examination staff has no way to verify your claims

There are different kinds of examinations which are used to determine the knowledge, skills, and abilities needed. Any one or a combination of tests may be given. The examination information is listed on the announcement. Below are examples of the type of examinations that can be given:

  • Application Evaluation: standard application and/or supplemental questionnaires, etc., are reviewed by an analyst or panel of subject matter experts to determine possession of required knowledge, skills, and abilities. All candidates are rated against the same criteria.

The County of Los Angeles may consider you for hire, if you pass the entire testing process including a review of your background.

Placement on this list does not guarantee you a job with the County of Los Angeles. As vacancies occur, you may be contacted directly by the hiring department. Candidates in the highest grouping/band are given first consideration. Your opportunity for appointment depends on the number of vacancies, the number of candidates in your band as well as the number of candidates in higher bands. A band is a grouping of fixed ranges, for example, 100-95, 94-90, etc. Each band may contain zero to many candidates based on their passing score. Be sure to provide updated contact information, otherwise you may miss future job opportunities.
