Police Character Certificates: What Applicants Must Prove

A police character certificate is a document issued by a police or criminal records authority that sets out whether you have a criminal history. It is not a standalone visa category. It is evidence used within a broader application, and what it must prove depends on the country and the route you are applying under. For Australian citizenship, the requirement is that you are of “good character”, and a nationally coordinated criminal history check is part of how that is assessed. For certain UK study and research routes, the equivalent requirement is an ATAS certificate, which is a security clearance rather than a police record check. You should not assume one certificate satisfies every application; the type of evidence, the issuing body, and the timing all differ by destination.

What a police character certificate actually proves

A police character certificate is evidence about your criminal history, not a general statement of your moral standing. The Australian Department of Home Affairs describes the “good character” requirement for citizenship applicants aged 18 and over as referring to the “enduring moral qualities of a person”. If you are found to be of good character, the department has considered that you are likely to uphold and obey the laws of Australia and other commitments you make through the pledge of commitment.

The criminal history information that can be considered includes charges, court convictions including penalties and sentences, findings of guilt with no conviction, court appearances, good behaviour bonds or other court orders, matters awaiting court hearing, warrants and/or warnings, and traffic offences. This is a broad list. A certificate is not simply a pass or fail document; the content is assessed against the character requirement.

When you need one for Australian citizenship

Applicants for Australian citizenship aged 18 years and over must be of “good character”. As part of this assessment, you may need to give the department a penal clearance certificate for countries you have visited outside Australia. The department also works with the Australian Criminal Intelligence Commission (ACIC) and Australian police agencies through the National Police Checking Service (NPCS).

The NPCS allows people to apply for a Nationally Coordinated Criminal History Check (NCCHC), which the department describes as an important part of the assessment of your citizenship application. The department forwards information from your citizenship application form to the NPCS and to Australian police agencies for checking action. These agencies include the Australian Federal Police, New South Wales Police Force, Victoria Police, Queensland Police Service, South Australia Police, Western Australia Police Force, Tasmania Police, and Northern Territory Police Force.

By signing the NPCS consent section in your citizenship application, in physical or electronic format, you are consenting to these agencies accessing their records to get criminal history information that relates to you. You also consent to them disclosing it to the department according to the laws of the relevant agency and in accordance with the relevant agency’s disclosure policy.

How a criminal record affects the outcome

Having a criminal record does not automatically mean you will not meet the good character requirement. The department assesses each case on its merits. This is a critical point: the certificate is evidence, not a verdict. Two applicants with superficially similar records can be assessed differently, depending on the nature of the offences, the time that has passed, and the conduct since.

The department also states that it cannot approve any applicant for citizenship by conferral, regardless of age, in certain circumstances relating to criminal offences. That means there are some offences that are disqualifying irrespective of any other favourable factors. The official guidance does not specify which offences those are, so you must check the current character requirements on the Department of Home Affairs website for the precise list.

It is in your interest to give full and accurate details in your citizenship application. Withholding or misstating a criminal history is likely to be treated as a separate and serious issue, quite apart from the underlying offence.

The UK ATAS certificate: a different kind of clearance

The UK’s Academic Technology Approval Scheme (ATAS) is often confused with a police character certificate, but it is not one. ATAS is administered by the Foreign, Commonwealth & Development Office (FCDO) and applies to certain foreign students and researchers who want to study or conduct research in specific sensitive technology-related fields in the UK. It is a security clearance based on your nationality, your subject area, and your proposed activity, not on your criminal record.

You do not need an ATAS certificate if you are studying for a postgraduate diploma or PGCE. You also do not need one if you have Indefinite Leave to Remain in the UK, if you are exempt from UK Immigration Control, or if ATAS does not apply to your specific visa conditions. For example, an individual will not need an ATAS certificate if they hold a valid Global Talent Visa for employment as a contracted researcher in the UK.

Nationals and citizens of a defined list of exempt countries do not need to apply. That list includes Australia, Canada, Japan, New Zealand, Singapore, South Korea, the United States, and most European countries. If you are a dual national and one of your nationalities is for an exempt country, you do not need an ATAS certificate. However, you must have a valid passport from an exempt country and a valid UK visa linked to it. Your Higher Education Institution or Research Institution may check this before the start of your taught course, research programme or employment.

When ATAS is required and how it fits your visa

Students and contracted researchers of all other nationalities that are not listed above must apply for an ATAS certificate if your taught course, research or employment requires it. Those applying for an undergraduate course with an integrated Masters year may also need ATAS clearance. If you are undertaking a taught course, research at Masters or PhD level, or employment, your subject area will have a Common Aggregate Hierarchy (CAH3) code, and your Higher Education Institution or Research Institution will typically include this on your official offer letter or confirm it separately. If you are a contracted researcher, the institution will also confirm if your employment has a Standard Occupational Classification (SOC) that requires an ATAS certificate.

For some visas you must have an ATAS certificate before applying for the visa, so it can be checked as part of your visa application. If your course or employment requires an ATAS certificate, you must get one before applying for a Student visa, Skilled Worker visa, Intra Company Transfer (ICT) visa, Global Business Mobility visa, Scale-up visa, Temporary Work – International Agreement visa, or Temporary Work – Government Authorised Exchange visa.

Other visas do not require you to provide an ATAS certificate at the point of making your visa application, but you must always obtain one before starting a programme or employment that requires it, as it will be checked by your institution. You do not need an ATAS certificate before applying for a Standard Visit visa, including visiting as an Academic.

If your certificate is rejected or disputed

The official guidance addresses two distinct situations. For Australian citizenship, the department notes that you have the right to dispute your police check result if you believe it is incorrect, and refers you to the ACIC’s appeals and disputes page. That is the route for challenging the content of the check itself, not for challenging the character decision. If the department refuses citizenship on character grounds, that is a separate decision with its own review process, which you should verify on the Home Affairs website.

For ATAS, the application statuses are defined. A refusal is when ATAS clearance is denied and an ATAS certificate will not be issued. A “requires changes” status is when an error is identified within the application; you can correct the mistake and resubmit, or withdraw. A “duplicate application” is when you try to submit a new application while an existing one is in a state of submitted, accepted, or changes required, and your date of birth, passport number, CAH3 code, and institution details are all identical. If your ATAS application is refused, the official guidance does not set out an appeal route; you should check the current guidance on GOV.UK for what options exist.

What to do next and what to verify

Before you rely on any certificate, confirm the exact requirement for your route on the official page, because the evidence you need is route-specific.

Route	Evidence needed	Issuing body	Timing
Australian citizenship (18+)	Nationally Coordinated Criminal History Check (NCCHC) plus penal clearance certificates for countries visited outside Australia	ACIC via NPCS, plus Australian police agencies; foreign authorities for overseas clearances	Part of the citizenship application; consent is given in the application form
UK Student, Skilled Worker, ICT, Global Business Mobility, Scale-up, Temporary Work – International Agreement, Temporary Work – Government Authorised Exchange	ATAS certificate	FCDO	Must be obtained before applying for the visa, if the course or employment requires it
UK Standard Visit visa (including Academic)	No ATAS certificate required at visa application stage	Not applicable	Must still obtain ATAS before starting a programme or employment that requires it

Verify the current character requirements on the Australian Department of Home Affairs website, including the specific offences that are disqualifying regardless of age. For ATAS, check the current guidance on GOV.UK, confirm your CAH3 code with your institution, and confirm whether your employment has a SOC code that requires ATAS. If you have any doubt about your criminal history, disclose it fully in your application rather than leaving it to be discovered.
