What positions does the LA County BBC exam qualify me for?

A passing score on the Broad-Based Clerical examination places you on a civil service eligibility list that can be used to fill a range of LA County clerical and secretarial classifications, including Secretary I/II, Intermediate Clerk Typist, Office Assistant I/II, and similar titles across county departments such as the Department of Public Works, Department of Health Services, Probation Department, and others. The specific positions you are referred to depend on which departments are actively hiring and your rank on the eligibility list.

How is the BBC exam scored and what is the passing score?

LA County DHR scores the BBC exam and ranks passing candidates on an eligibility list by their final score. The passing threshold varies by exam administration and is set by the county, but candidates who score higher are referred to departments first. There is no published minimum passing percentage — the practical cutoff is wherever the county has enough candidates to fill current vacancies. Scoring as high as possible maximizes your chances of being referred quickly.

Is the BBC exam timed and can I use a calculator?

The BBC exam is timed, and time management is important — the arithmetic section in particular requires working accurately under pressure. Calculator use is generally not permitted during the written examination, so practicing mental math and paper-based arithmetic before your exam date is essential. Check your specific exam notice from LA County DHR for any materials or accommodations allowed at your testing session.

How long is the BBC eligibility list valid and can I retake the exam?

LA County civil service eligibility lists are typically valid for one to two years from the date they are established, though the county may extend or abolish a list based on hiring needs. If the list expires before you are referred, you would need to retake the BBC exam to re-establish eligibility. Candidates who did not pass may also retake the exam after the county-specified waiting period, which is usually stated in the original exam bulletin.

BBC Exam Fast Facts

What the LA County BBC Exam Covers

The BBC exam is designed to measure the practical skills needed to perform clerical and secretarial duties in a large public-sector organization. The questions reflect real tasks that office staff encounter daily in LA County departments.

Reading Comprehension

Passages drawn from county policy memos, procedure manuals, and interoffice correspondence test your ability to identify the main idea, draw inferences, apply written instructions to hypothetical scenarios, and understand unfamiliar vocabulary in context. Strong readers who can work through dense procedural language quickly have a significant advantage on this section.

Written Communication: Grammar, Spelling, and Punctuation

Questions ask you to identify grammatical errors in sentences (subject-verb agreement, pronoun case, modifier placement), select the correctly spelled word from a set of options, and apply punctuation rules (commas in series, apostrophes for possessives, colons and semicolons in compound sentences). Professional memo and letter format — inside address, salutation, body, complimentary close — is also tested.

Arithmetic Computation

Expect questions on addition, subtraction, multiplication, and division of whole numbers, fractions, and decimals. Percentage calculations (finding a percentage of a number, calculating percent increase or decrease) and basic statistics (computing an average/mean) appear regularly. Invoice calculations, petty cash reconciliation, and timesheet math are common real-world applications tested in this section.

Data Checking and Comparison

You are shown two versions of a record — a source document and a typed entry — and must identify whether they match exactly or locate the specific discrepancy (transposed digits, wrong letter, different spacing). Alphabetical filing order questions test whether you can sequence names correctly using standard library-style rules (last name first, letter-by-letter comparison, handling prefixes like Mc/Mac and hyphenated names).

Office Procedures

Topics include telephone etiquette (how to screen calls, take accurate messages, transfer calls professionally), records management principles (retention schedules, active vs. inactive files, destruction procedures), appointment scheduling and calendar management, and standard office equipment operation. Understanding when to escalate an issue to a supervisor vs. handle it independently is a recurring theme.

Filing Systems

Questions cover alphabetic, numeric, geographic, and subject filing systems. You must know the rules for alphabetizing under ARMA (Association of Records Managers and Administrators) standards — nothing before something, units in sequence, special characters, government names — and understand when numeric filing (terminal digit, consecutive) is preferable to alphabetic.

Customer Service and Interpersonal Skills

Scenarios present difficult public interactions — an irate caller, a visitor without an appointment, a request for information you cannot provide — and ask you to select the most appropriate professional response. The exam emphasizes de-escalation, empathy, accurate information-giving, and maintaining a positive image for the county department.

Basic Computer and Keyboarding Knowledge

Questions test general computer literacy: understanding file management (saving, naming, organizing documents), basic word processing concepts (formatting, spell-check, mail merge), spreadsheet awareness (sorting, basic formulas), email etiquette, and data entry accuracy. Keyboarding speed and accuracy may be tested separately in a typing component depending on the specific position.
