TL;DR: ADAS stands for Administrative Assistant. It is a position code, not an acronym anyone coined for convenience, and you can see it inside the plantilla item number on any DepEd vacancy announcement, for instance
OSEC-DECSB-ADAS3-17-2015. Its neighbours in the same ladder are ADA (Administrative Aide) and ADOF (Administrative Officer). On DepEd's own published vacancies, Administrative Aide VI sits at Salary Grade 6, Administrative Assistant II at Salary Grade 8, Administrative Assistant III at Salary Grade 9, Administrative Officer I at Salary Grade 10 and Administrative Officer II at Salary Grade 11.
If you have seen "ADAS III" in a division memo, on an office door or in a group chat about vacancies and had no idea what it meant, you were not being slow. The Department uses item codes constantly in internal traffic and almost never expands them. This guide explains where the code comes from, what separates the three administrative families, what the published qualification standards actually say, and which issuance governs hiring into these positions.
Where the Abbreviation Comes From
Every plantilla position in the national government carries an item number, and DepEd prints it on the vacancy announcement. A real one from a DepEd Legal Service posting reads:
OSEC-DECSB-ADAS3-17-2015
Read it in parts. The leading segments identify the agency and office grouping the item belongs to. ADAS3 is the position code and level: Administrative Assistant III. The trailing numbers are the item serial and the year the item was created. The same pattern produces ADA6 for Administrative Aide VI, ADOF1 for Administrative Officer I, ADOF2 for Administrative Officer II and ADOF4 for Administrative Officer IV.
That is the whole mystery. ADAS is not a programme, a system or a training course. It is four letters standing in for two words on a payroll line.
ADA, ADAS and ADOF Side by Side
The three families form a progression in scope and in entry requirement. Here is what DepEd's own published vacancy announcements state for the levels we could verify directly:
| Position (item code) | Salary Grade | Education required | Experience | Training | Eligibility |
|---|---|---|---|---|---|
| Administrative Aide VI (ADA6) | 6 | Completion of 2 years of studies in college | None required | None required | Career Service (Sub-professional), First Level |
| Administrative Assistant II (ADAS2) | 8 | 2 years of college, or high school graduate with relevant vocational or trade course | 1 year relevant | 4 hours relevant | Career Service (Sub-professional), First Level |
| Administrative Assistant III (ADAS3) | 9 | Completion of 2 years of studies in college | 1 year relevant | 4 hours relevant | Career Service (Sub-professional), First Level |
| Administrative Officer I (ADOF1) | 10 | Bachelor degree relevant to the job | None required | None required | Career Service (Professional), Second Level |
| Administrative Officer II (ADOF2) | 11 | Bachelor degree | None required | None required | Career Service (Professional), Second Level |
| Administrative Officer IV (ADOF4) | 15 | Bachelor degree | 1 year relevant | 4 hours relevant | Career Service (Professional), Second Level |
Two things fall out of that table. First, the hard boundary between ADAS and ADOF is the degree and the eligibility: sub-professional first level for Administrative Assistant, professional second level for Administrative Officer. If you are deciding which exam to sit, that is the decision. Our explainers on civil service eligibility and on the professional versus sub-professional exam cover the difference in detail.
Second, requirements are published per vacancy, and offices do add preferred qualifications above the minimum. The Administrative Officer IV posting we checked listed preferred qualifications of a relevant bachelor degree, two years of experience and 24 hours of training on top of the minimum. Always read the announcement in front of you rather than a generic list, including this one.
Disclaimer: salary grades are stated as printed on DepEd vacancy announcements. The peso amount attached to any grade changes with the compensation schedule, so check the current schedule rather than an old announcement.
Why the Position Has Two Titles
Look at real DepEd postings and you will see entries like these:
- Administrative Assistant III (Secretary II)
- Administrative Assistant III (Computer Operator II)
- Administrative Assistant II (Data Entry Machine Operator II)
- Administrative Officer I (Cashier I)
The name outside the brackets is the plantilla position title, and it is what determines the salary grade and the qualification standards. The name inside the brackets is the functional title, describing what the person actually does in that office. A "Secretary II" and a "Computer Operator II" can both be Administrative Assistant III at Salary Grade 9 because the plantilla title is the same and the work is not.
This is why searching for a job title alone gives inconsistent answers. Search the item code.
What the Work Looks Like
The job descriptions printed on DepEd vacancy announcements are short and consistent in shape. The Administrative Aide VI posting at Baguio Teachers' Camp describes the position as responsible for the delivery of prompt and quality administrative and clerical support to the Division in accordance with the Department's policies and procedures. The Administrative Assistant III posting at the Legal Service describes providing assistance in the delivery of prompt and quality administrative and clerical support to the Office of the Director.
The pattern is that the level tells you the scale and the supervision, not a different kind of task. Administrative support work in DepEd sits inside the same office you are supporting, whether that is a bureau at Central Office, a service in a regional office, or a schools division office. If you want the map of those offices, our Schools Division Office guide and the DepEd regional and division offices overview set out the structure.
Which Issuance Governs Hiring
DepEd Order No. 007, s. 2023, the Guidelines on Recruitment, Selection, and Appointment, is the current framework, and it has been amended by DepEd Order Nos. 020 and 021, s. 2024. DepEd vacancy announcements themselves point applicants at it and require them to read specific parts, in particular:
- Section V of Enclosure 1, covering publication and posting of vacancies, submission and receipt of application documents, initial evaluation, comparative assessment and appointment;
- Enclosure 5, the Criteria and Point System for Hiring and Promotion to Non-Teaching Positions.
The practical consequence is that an ADAS application is scored, not simply screened. Knowing where the points sit before you assemble your folder is worth more than any template letter. Our letter of intent guide covers the covering document that announcements typically ask for.
Practical Checks
- Search the item code, not the job title.
ADAS2,ADAS3,ADOF2will find you the exact level; "admin assistant DepEd" will not. - Match the eligibility before anything else. Sub-professional first level opens ADA and ADAS. Professional second level is what ADOF needs.
- Treat peso figures on old announcements as historical. The salary grade is durable; the amount attached to it is not.
- Read the bracketed title. It tells you what you will actually be doing all day.
- Check the issuing office. Central Office, regional office and schools division office vacancies all use the same codes but different submission routes.
