In short
- Use only the current Z83 (introduced in 2021), filled in for one post, signed and dated.
- Answer every question. Write N/A where something does not apply. Never leave blanks.
- Quote the exact post title and reference number, and send it to the exact address in the advert.
- Do what the advert says about documents. Too little and too much can both cause problems.
It is one of the most painful facts about public service recruitment in South Africa: many applications are never really read. When a post attracts hundreds or thousands of applicants, the first step is often a screening check. Applications that break the rules in the advert, or that use the wrong form, are set aside. Only the ones that pass that check go on to be compared against the requirements, and only after that does a panel draw up a shortlist.
The good news is that almost every reason for failing that first check is within your control. This guide covers the twelve mistakes we see most often in government applications, why each one matters, and exactly what to do instead. If you have not filled in a Z83 before, start with our Z83 form explained guide, then come back to this one as a final check before you submit.
1. Using an old version of the Z83
The public service introduced a new Z83 form in 2021, and adverts state clearly that applications on the old form will not be considered. Many people still have the old one saved on their phone or computer, or copy it from a friend.
What to do: Download the Z83 fresh from the DPSA website, or from the department you are applying to, and keep that copy as your template. The new form is laid out differently and includes questions the old one did not have, so it is easy to spot if you compare them side by side.
2. Leaving parts of the form blank
A blank space is the most common reason a Z83 is treated as incomplete. Panels cannot tell whether you skipped a question by accident, chose not to answer, or meant that it does not apply.
What to do: Answer every question. If something genuinely does not apply to you, write "N/A" (not applicable). For example, if you do not have a professional registration, write N/A in that field rather than leaving it empty. Before you submit, go through the whole form once looking only for empty spaces.
3. Not signing or dating the form
An unsigned Z83 is not a valid application. The signature is your declaration that the information is true. It sounds obvious, but it is easy to forget when you are filling in several forms in one evening, or when you type the form and forget to sign it after printing.
What to do: Sign and date every Z83 in the place provided, every time. If you scan the form to email it, check that the signature is clearly visible in the scan.
4. Using one form for several posts
Some applicants fill in a single Z83 and list two or three posts on it, or send one email that applies for several jobs. Each post is normally shortlisted separately, often by a different panel, so an application that mixes posts may end up being considered for none of them.
What to do: Send a separate application for each post, each with its own Z83 showing that post's title and reference number. Keep a master copy so that you only need to change the post details each time.
5. Wrong or missing reference number
Departments often advertise many posts at once, and the reference number is how your application reaches the right file. A missing or mistyped reference number can send your application to the wrong post, or nowhere.
What to do: Copy the reference number exactly as it appears in the advert, including letters, slashes and dashes. If you apply by email, put the post title and reference number in the subject line too, unless the advert asks for a different format.
6. Sending it to the wrong place
The application address in a government advert can be different for every post, even within the same department. A hospital post may go to the hospital, a district post to the district office, and a head office post to head office. Some departments accept only online applications through their own system.
What to do: Use the address under "Applications" for the specific post you want, not one you used before. If the advert says applications must be made online, do not email or post a paper application as well.
7. Not meeting a compulsory requirement
Shortlisting is usually done by checking each requirement in turn. If the advert asks for a specific qualification, a number of years of experience in a certain area, a driver's licence or a professional registration, and your application does not show it, you are normally not shortlisted.
What to do: Before you apply, go through the requirements line by line and tick off each one. Make sure your CV clearly shows the evidence for each requirement, with dates. If you have exactly the experience asked for, make it easy to see: "Finance clerk, 2022 to 2025, three years" is clearer than a vague list of duties.
8. Ignoring the document instructions
Departments have different rules about documents. Many now ask for only the Z83 and a CV at first, and request certified copies of your ID and qualifications only from shortlisted candidates. Others still ask for certified copies with every application. Some also ask for specific extras, such as proof of professional registration or an academic record.
What to do: Read the department's introduction and the post's note, and send exactly what is asked. If certified copies are needed, make sure they are certified properly; our certified copies guide explains how.
9. Unanswered or dishonest declaration questions
The Z83 asks questions about matters such as previous dismissals, pending cases and conduct. Some applicants skip them because they are uncomfortable, and some give answers that are not true, hoping nobody checks. Appointments in the public service are usually subject to background checks, and a false declaration is treated far more seriously than an honest answer.
What to do: Answer every declaration question truthfully. If a "yes" needs explaining, use the space provided to explain briefly and factually.
10. A CV that does not match the Z83
Panels compare the Z83 and the CV. If the dates, job titles or qualifications on the two do not match, it raises questions about accuracy, and it makes your application harder to assess.
What to do: Write your CV first, then fill in the Z83 from it, so that names, dates and qualifications are the same on both. Include full dates (month and year) for every job, the name of each employer, and contactable references.
11. Applying at the last minute
Closing dates in government adverts are strict. Applications that arrive after the closing date, or after the closing time where one is stated, are not considered, whatever the reason. Email systems can be slow on the closing day, and posted applications can take longer than expected.
What to do: Aim to submit at least two or three days before the closing date. If you are posting your application, allow even more time and keep proof of postage.
12. Unreadable or badly scanned documents
A blurry photo of a Z83 taken at an angle, or a scan where half the page is missing, can make your application impossible to assess. This is especially common when people apply from their phones.
What to do: Use a scanning app that flattens the page and improves contrast, or a proper scanner. Save the Z83 and CV as clear PDF files, and name them sensibly, for example "Z83_Thandi_Mokoena_Ref_ADMIN-2026-14.pdf". Open each file before sending to check that every page is readable.
A final checklist before you submit
- I am using the current Z83, downloaded fresh.
- This Z83 is for one post only, with its exact title and reference number.
- There are no blank spaces. N/A is written where something does not apply.
- All declaration questions are answered honestly.
- The form is signed and dated.
- My CV and Z83 show the same names, dates and qualifications.
- I meet every compulsory requirement, and my CV shows it clearly.
- I have attached exactly the documents the advert asks for, certified if required.
- I am sending it to the exact address or system given for this post.
- I am submitting well before the closing date.
Working through this list takes five minutes, and it removes almost every reason for an application to be set aside before it is read. After that, it is your qualifications and experience that decide whether you are shortlisted, which is exactly how it should be. When you are ready, you can find current public service posts on our government jobs page.
Questions people ask
Can I type my Z83 instead of writing it by hand?
Yes, the Z83 can be completed electronically, and a neat typed form is often easier to read. What matters is that it is complete and signed. If you type it, you still need to sign it, either by hand after printing or with a clear signature if the department accepts electronic submissions.
Do I need to fill in the qualifications and experience parts if I attach a CV?
Under the current Z83, if the advert asks for a CV, you generally do not have to repeat all your qualifications and work history on the form, because the CV carries that detail. You must still complete every other part of the form. If the advert does not ask for a CV, complete those sections fully.
Is it a problem if I answer 'yes' to a declaration question?
Not automatically. Questions about previous dismissal or conduct are there so the department can consider the full picture. What is treated seriously is a false answer. If your situation needs explaining, answer honestly and give the brief explanation the form allows.
Should I send certified copies just in case?
Only if the advert asks for them at the application stage. Many departments now ask for certified copies only from shortlisted candidates, and some specifically say not to send them upfront. Follow the instructions for that post.
