ACS Assessment Documents: What You Need to Prepare

The Australian Computer Society (ACS) skills assessment is a critical step for IT professionals seeking to migrate to Australia through skilled migration visas. Whether you're applying for a Skilled Independent visa (subclass 189), Skilled Nominated visa (subclass 190), or Skilled Work Regional visa (subclass 491), you'll need to submit a comprehensive set of documents to prove your IT qualifications and work experience. This checklist covers everything the ACS requires, so you can prepare your application correctly the first time.

The ACS assessment process is strict. Missing documents or incomplete information can result in delays, requests for further evidence, or outright rejection. Understanding exactly what to submit saves time and money. This guide breaks down each required document into clear sections so you know precisely what to gather before you start your application.

Identity and Passport Documents

Your identity documents form the foundation of your ACS application. The ACS needs to verify who you are and confirm your legal right to work and study in countries where you claim experience.

You must provide a certified copy of your passport. The certification must be done by an authorised person such as a notary public, lawyer, or justice of the peace. A simple photocopy is not acceptable. If your passport has expired, you still need to submit it alongside your current passport to show your full identity history. Some applicants have multiple passports if they've changed citizenship or renewed their documents. Include all of them.

If you have a national ID card from your home country, include a certified copy. This is especially important if your passport doesn't show all your work history dates clearly. The ACS uses these documents to cross-reference your employment claims and verify your identity against your reference letters.

Educational Qualifications and Transcripts

Your IT qualifications are central to the ACS assessment. You need to prove you have the right level of education in an IT-related field.

Gather official transcripts from every university, college, or technical institute where you studied IT. Transcripts must be official documents issued directly by the institution, not printed from a student portal. If your institution uses a digital transcript system, request an official digital copy with a tamper-proof seal or verification code. The ACS will often contact your university to verify transcripts, so make sure the documents you submit match the institution's records exactly.

Include your degree certificate or diploma. Again, this must be an official certified copy. If your certificate is in a language other than English, you must provide an official English translation completed by a NAATI-accredited translator or equivalent. The ACS does not accept machine translations or translations done by friends or family members.

If you completed a postgraduate qualification (Master's degree, Graduate Diploma, or similar), include those transcripts and certificates as well. The ACS uses your highest qualification to assess your educational level and may give additional weight to postgraduate IT qualifications.

Some applicants completed IT training through online courses, bootcamps, or private institutions. If these are relevant to your claimed IT skills, include certificates of completion. However, the ACS prioritises formal university qualifications. Online certificates alone are unlikely to meet the educational requirement unless you also hold a formal IT degree.

Employment References and Work History Documentation

Employment references are the most critical part of your ACS application. The ACS needs to verify that you actually worked in IT roles for the duration you claim. Weak or missing references are the most common reason for ACS assessment rejections.

You need a reference letter from each employer where you claim IT work experience. The letter must be on official company letterhead and signed by a manager or HR representative who can verify your employment. The reference should include your job title, the dates you worked (start and end dates), a description of your IT duties, and confirmation that the writer supervised or worked closely with you. A generic letter saying "John worked here from 2018 to 2020" is not enough. The ACS wants specific detail about what you actually did.

If your employer is no longer in business or you cannot contact them, you may provide alternative evidence. This could include payslips, tax documents, employment contracts, or statutory declarations from colleagues who worked with you. However, the ACS prefers formal employer references. If you're using alternative evidence, explain clearly why you cannot obtain an employer reference.

For each role you claim, gather supporting documents. Payslips from that employment period are valuable. They confirm you were paid for the work and show the dates you were employed. Tax documents such as income tax returns or tax assessment notices also verify employment and income. Some countries issue employment certificates from tax authorities. If your country does this, obtain a copy.

Employment contracts are helpful, especially if they clearly describe your IT responsibilities. However, contracts alone don't prove you actually performed the work. Combine them with payslips or references.

If you worked as a contractor or freelancer, the process is different. You need evidence of contracts with clients, invoices you issued, and bank statements showing payments received. The ACS is more cautious with contractor claims because they're harder to verify. Provide as much documentary evidence as possible.

Skills and Technical Competency Evidence

Beyond your employment history, the ACS wants evidence that you actually have the technical skills you claim. This is where many applicants struggle because they overstate their abilities.

If you hold professional certifications (Microsoft, Cisco, AWS, Google Cloud, etc.), include copies of your certification documents. These are valuable because they're issued by independent third parties and verify specific technical knowledge. Include the certificate, the certification ID, and if possible, a link to the issuer's verification system so the ACS can check your certification is current and legitimate.

Include a detailed curriculum vitae (CV) that clearly maps your work history to the ACS occupation you're applying for. Your CV should list every IT role, the dates, the company, and a paragraph describing your specific technical responsibilities. Don't just say "IT Support". Say "Provided Level 2 technical support to 150 users, troubleshot Windows and Mac operating systems, managed ticket system, resolved network connectivity issues". The more specific you are, the more credible your application becomes.

If you've completed significant IT projects, include documentation. This could be project reports, code samples (if you're a developer), system designs, or project completion certificates. If you managed IT infrastructure, include network diagrams or system documentation you created. These artifacts prove you have hands-on technical experience, not just theoretical knowledge.

Some applicants include references from colleagues or clients who can attest to their technical abilities. While not required, these can strengthen your application if they're detailed and specific. A colleague's letter saying "I worked with John on several projects and he's a skilled developer" is more useful than a generic character reference.

Language Proficiency Evidence

The ACS requires evidence that you can work in English. If English is not your first language, you need to prove your proficiency.

If you completed your degree in English at a university in an English-speaking country (Australia, UK, USA, Canada, New Zealand, Ireland, South Africa), you may be exempt from English testing. Provide your degree certificate and transcript as evidence. The ACS will accept this as proof of English proficiency.

If you studied in a non-English-speaking country, you need to take an English language test. The ACS accepts IELTS, TOEFL, Pearson Test of English (PTE), or Cambridge English. You need to meet the minimum score for your occupation. For most IT occupations, this is IELTS 6.0 overall (with no band lower than 5.5), or equivalent in other tests. Include a copy of your test results with your application. The test must be taken within three years of your ACS application.

If you're a citizen of an English-speaking country (UK, USA, Canada, New Zealand, Ireland, South Africa, or similar), you may be exempt from English testing. Check the ACS website to confirm your country qualifies.

Additional Documents and Declarations

Beyond the core documents, the ACS requires several supporting items to complete your application.

You need to complete the ACS skills assessment application form. This is available on the ACS website. The form asks detailed questions about your education, work history, and technical skills. Answer every question thoroughly. Vague or incomplete answers raise red flags with assessors.

The ACS requires a statutory declaration confirming the accuracy of your application. This is a legal document where you swear under oath that the information you've provided is true and correct. You sign this in front of a notary public, lawyer, or justice of the peace. False information in a statutory declaration is a serious matter and can result in visa cancellation if discovered later.

If you have any gaps in your employment history, explain them. If you took time off work, were unemployed, or changed careers, document this clearly. The ACS understands that people have career breaks. What they don't like is unexplained gaps that suggest you're hiding something.

Include a cover letter explaining your application. This is your chance to tell your story. Explain why you're applying for the ACS assessment, what IT role you're targeting, and how your experience matches that role. Keep it concise (one page) but make it personal and genuine.

Document Preparation and Submission Tips

Preparing your documents correctly is as important as having the right documents. The ACS is strict about format and presentation.

All documents must be in English or accompanied by an official English translation. If a document is in another language, have it translated by a NAATI-accredited translator (in Australia) or equivalent professional translator in your home country. The translator must provide a certified translation with their credentials and signature.

Scan all documents clearly. Use a document scanner or high-quality phone camera. Make sure text is legible and colours are accurate. Blurry or dark scans may be rejected. Save files as PDF where possible. The ACS prefers PDF format because it preserves formatting and is harder to tamper with.

Organise your documents in a logical order. Create a folder for each section (identity, education, employment, skills, language). Number your documents. Create an index listing every document you're submitting. This helps the ACS assessor find what they need and shows you've prepared thoroughly.

Check the ACS website for the current submission method. As of 2026, the ACS accepts online submissions through their portal. Upload your documents according to their file size limits and format requirements. Keep a copy of everything you submit for your records.

Before you submit, do a final check. Verify that every document is certified or translated where required. Check that your employment dates are consistent across all documents. Make sure your CV matches your employment references. Look for any spelling errors or inconsistencies in your name or dates. A single error can trigger a request for clarification and delay your assessment.

Common Document Mistakes to Avoid

Many applicants make preventable mistakes that delay or derail their ACS assessment. Learning from others' errors can save you months of waiting.

Don't submit uncertified copies of your passport or degree. The ACS will reject these and ask you to resubmit. Certification must be done by an authorised person in your country or in Australia. Plan for this to take 1-2 weeks.

Don't use generic employment references. If your reference letter is vague or doesn't describe your specific IT duties, the ACS will contact your employer for clarification. This delays your assessment. Ask your referee to be specific about your technical responsibilities.

Don't claim work experience you can't prove. If you claim five years of IT experience but can only provide references for two years, the ACS will only count the two years you can verify. Be honest about what you can document.

Don't submit documents in languages other than English without translation. Even if you think the ACS assessor might speak your language, they won't read untranslated documents. Always provide official English translations.

Don't wait until the last minute to gather documents. Some documents take weeks to obtain. Your university might take two weeks to issue official transcripts. Your employer might take three weeks to write a reference. Start collecting documents at least two months before you plan to submit your application.
