Weekly hours worked. That single line is the field most often missing from an ACS employment reference letter, and its absence stalls assessments that are otherwise complete. Applicants polish the duties description and the dates, then forget the number the assessor scans for first. You do not need a paid CDR or RPL writing service to get this right. Match every field the ACS InfoHub actually requires, and most of the pages ranking for this topic quietly drop two of them.
This guide names each mandatory field, explains who can sign, sets out the statutory declaration fallback for unresponsive employers and closed companies, and lists the specific gaps that trigger rejection. Work through it once, and your letter will be ready to submit.

What ACS Assessors Actually Check in Your Reference Letter
Each letter is read for one purpose: confirming that the employment you claim is real, ICT-relevant, and tied to the occupation you nominated. Assessors match your dated work periods against your nominated ANZSCO code and decide how much of that experience counts toward your skilled employment date, the point after which your work starts earning migration points. A letter that is undated, vague, or copied from a template gives the assessor nothing to verify, and experience that cannot be verified is treated as no experience at all.
Submit a separate letter for every work period you want counted. One career-summary letter covering multiple roles is not accepted. Nor can you swap in a different document to save time: the ACS InfoHub employment references page states that employment contracts, offer letters, and position descriptions are not accepted in place of a reference letter. When a signed letter is genuinely unobtainable, a statutory declaration covers the gap, but only under the conditions set out further below.
For the full list of supporting documents that sit alongside the letter, see the ACS skills assessment document checklist; this guide stays on the letter itself.
Every Mandatory Field an ACS Employment Reference Letter Must Include
Thirteen fields. The ACS InfoHub employment references page requires all of them, and a letter missing any single one is incomplete. Most competitor templates cover seven or eight. The two they almost always drop are annual salary before tax and the company website URL, and both are mandatory:
- Company letterhead, with the company website URL printed on it
- Your full legal name
- The date of the letter, written DD/MM/YYYY
- Your employment start and end dates, also DD/MM/YYYY
- Employment status: permanent full-time, part-time, or contract
- Minimum weekly hours worked
- Annual salary before tax
- Work location, stated as inside or outside Australia
- Your exact position title at that employer
- A bullet-point description of your ICT duties
- The signatory's signature carrying a digital verification certificate
- The signatory's full name and position title
- The signatory's direct phone number and work email
Two fields carry caveats. Salary before tax is required, but the InfoHub qualifies it with your company's guidelines, so include it where your employer's disclosure policy permits and note the policy where it does not. Dates are the other trap: DD/MM/YYYY means exactly that. Not "March 2019", not ISO-style 2019-03, and not a bare range like "2019 to 2022". Ambiguous dates are one of the fastest routes to a follow-up request.
Below is a side-by-side comparison of what ACS asks for against the gap that most often appears in rejected letters. This comparison is acsskillsassessment.com's own analysis, built from the InfoHub field list and publicly documented assessment outcomes:
| Mandatory field | Common gap in rejected letters |
|---|---|
| Minimum weekly hours | Omitted entirely, or given as a vague "full-time" |
| Employment dates DD/MM/YYYY | Written as "Month Year" or an undated range |
| Company website URL | Absent from the letterhead |
| Annual salary before tax | Left out with no policy note |
| Signatory work email | A personal Gmail or Yahoo address used instead |
| Duties description | Copied word-for-word from the ANZSCO code |
| Digital signature | A pasted image with no verification certificate |
Who Can Sign the Letter, and the Statutory Declaration Fallback
A former manager left the company two years ago, HR takes a week to reply, and the office you worked in has been absorbed into another entity. Start with who ACS will actually accept as a signatory. Direct supervisors, HR managers, and company directors can all sign, as long as they can attest to your day-to-day work. Their contact details must be a work email and a direct phone number. Personal email addresses are explicitly prohibited by the InfoHub, so a manager who signs off with a private account invalidates the letter.
Contractors face a particular trap. On a recruitment-agency or labour-hire arrangement, the letter must come from the host company you were contracted into, not from the agency that placed you. The agency did not observe your duties; the host did.
When no signatory is reachable, a statutory declaration substitutes, and the authorship rule is where applicants go wrong. For an employed role, you cannot write your own declaration. According to the ACS InfoHub, it must be written and signed by a work colleague in a managerial or supervisory position who observed your duties; self-references from the applicant are rejected outright for employment scenarios. The declaration must carry all thirteen fields a normal letter would, along with the witnessing language: the phrase "Sworn Before", "Signed Before", or "Witnessed Before" an authorised witness such as a Justice of the Peace, together with that witness's signature, the date, and the place of witnessing. A missing witnessing block voids the document.
One document most guides never mention: an employed applicant relying on a statutory declaration must also supply a separate employment certificate or statement of service showing start dates in DD/MM/YYYY. The declaration alone is not enough.
Self-employed applicants sit under a different rule. Writing your own declaration is permitted, but you must back it with business registration certificates, accountant statements, client statements, payment evidence, and contracts.
Drafting Each Section of a Compliant ACS Employment Reference Letter
Build the letter in three blocks, and the fields fall into place.
The opening states who you are and the shape of the role: your full name, your exact title, who you reported to, and your employment dates in DD/MM/YYYY. One paragraph, no preamble.
The duties block is where the assessment is won or lost, and it carries one hard prohibition. Map your work to your nominated ANZSCO occupation, but never copy the ANZSCO text. ACS rejects duties lifted verbatim from the code or from another reference letter, even when the role genuinely matches. Write in operational language and keep it concrete: "designed and maintained relational databases supporting a 40,000-user platform", "developed and tested REST APIs for the payments service", "administered Linux production servers and led incident response". Generic phrasing like "performed various IT duties" tells the assessor nothing.
The closing block carries the signatory's full name, position title, direct phone number, and work email, followed by the signature with its digital verification certificate. A digital signature is ACS's stated preference, provided the certificate authenticates the signer. A scanned image of a handwritten signature dropped into a typed letter, with no certificate behind it, does not satisfy the requirement.
Overseas Employers, Translations, and Companies That Have Closed
Two different problems get bundled together here, and they take different routes.
When the employer still exists but the letter is not in English, you need a certified translation. Within Australia, use a translator accredited by NAATI. The ACS document translation page accepts a second path for documents translated outside Australia: a translation from the Awarding Institution, carrying an official stamp, the translator's name and signature, and contact details on the organisation's letterhead. An Australian diplomatic or consular mission can point you to an accredited translator in your country, but a translation sourced from the mission itself is not an accepted source. Informal or unaccredited translations are rejected either way.
When the company has shut down, no one can sign a letter, so you move to the statutory declaration route from a former manager or supervisor. Support that declaration with whatever independent evidence you can assemble: payslips, tax records, superannuation statements, or a business registry record showing the company existed and when it ceased. The declaration proves the duties; the paper trail proves the employment.
Seven Reasons ACS Rejects an Employment Reference Letter
Most rejections trace back to a short, predictable list. Fix these before you submit:
- Missing or ambiguous dates and no weekly hours. The two fields assessors check first, and the two most often fumbled.
- Duties copied from the ANZSCO code. An automatic rejection, regardless of how well the role fits.
- A personal email for the signatory. Only a work address is accepted.
- A letter on plain paper. No letterhead means no verifiable company identity and no assessment.
- A pasted signature image with no verification certificate. The letter looks signed; it does not authenticate.
- A statutory declaration from the applicant or a junior colleague. For employed roles, it must come from a manager or supervisor whose dates overlap yours.
- A contract or offer letter submitted instead of a reference. These are never accepted as substitutes.
FAQs About the ACS Employment Reference Letter
Can my employer sign digitally, or must it be handwritten?
A digital signature is ACS's preferred option, as long as it carries a verification certificate that authenticates the signer. A scanned or pasted image of a handwritten signature, with no certificate metadata behind it, does not meet the requirement. Handwritten-then-scanned is weaker than a properly certified digital signature, not stronger.
What if my previous employer has closed and cannot sign a letter?
Submit a statutory declaration in place of the letter. For an employed role, it must be written and signed by a former manager or supervisor who observed your work, witnessed by an authorised person such as a Justice of the Peace, and it must repeat every field a standard letter carries. Support it with payslips, tax records, or a business registry record confirming the company existed.
Must reference letters be in English, and how are they translated?
Non-English letters require a certified translation. Within Australia, the translator must be accredited by NAATI. For documents translated outside Australia, ACS also accepts a translation from the Awarding Institution, provided it carries an official stamp, the translator's details, and a signature on letterhead. An Australian diplomatic or consular mission can help you find an accredited translator in-country, but it is not itself an accepted translation source. Informal translations are not accepted.
Does ACS need a letter for every job, or only my nominated occupation?
You need a letter for every employment period you want counted toward your skilled experience. Roles you are not claiming do not require one. Because ACS credits experience against your nominated ANZSCO occupation, the periods that matter are the ones whose duties map to that code. Confirm which periods you are claiming through the ACS skills assessment pathways explained guide.
Can I reuse the same letter if my assessment expires and I reapply?
ACS does not state an expiry on the reference letters themselves, so an older letter may still be usable on a fresh application. Verify it against the current InfoHub field list before resubmitting, since requirements are updated periodically and a letter written for an earlier application may be missing a field added since.
