by Kylie Evans, Head of Admissions Operations, Aberystwyth University
Over the past year, I’ve been learning more about AI, and thinking about how it could be used to assist with manual, rules-based tasks. As part of that journey, I decided to experiment with creating a custom GPT for tuition fee status assessments to support our Admissions team at Aberystwyth University.
If you’ve ever worked in admissions, you’ll know that deciding whether a student should be classified as Home or International for fee purposes isn’t always straightforward. Considerations include legislation, immigration categories, ordinary residence rules, and careful interpretation of evidence. It’s technical, highly regulated, and sometimes surprisingly nuanced.
That complexity is exactly what made me think this might be a good test case. Fee status decisions are largely rules-based: you’re applying defined categories to a set of facts. Does the applicant have settled status? Have they been ordinarily resident in the relevant area for three years? Was any time abroad a temporary absence? Was residence mainly for education?
It’s structured. It’s logical. It requires consistency.
So, I built the Tuition Fee Status Assessment GPT as a decision-support assistant. The aim was never to replace staff or automate professional judgement. Instead, it was to explore whether a custom GPT for tuition fee status decisions could help structure complex reasoning, apply the rules consistently, and produce clear, audit-ready outputs. Importantly, this tool is still in its early testing phase, but having tested a number of iterations of the model, initial outputs look promising.
This approach is not limited to ChatGPT
While this project was built as a custom GPT for tuition fee status assessments in OpenAI’s ChatGPT, the same methodology and prompt can be replicated across other major AI platforms. You could set this up as a Custom Agent in Microsoft Copilot, a Gem in Google Gemini, or a Project in Anthropic’s Claude. The principles are the same: define your rules clearly, structure the governance framework, and provide it as system instructions. The platform is just the vehicle.
What the GPT Does
The GPT takes a scenario equivalent to what would be captured in a Fee Status Assessment Questionnaire and works through it methodically. It identifies the relevant fee status categories, tests each requirement individually, and produces a structured outcome: Home, International, or Provisional if the evidence is incomplete.
Each output is deliberately transparent. It sets out which category has been considered, which tests have been applied, what evidence is present or missing, and provides a short rationale that could stand up to audit scrutiny.
It doesn’t make assumptions beyond the facts provided, and it’s intentionally cautious, escalating uncertainty and defaulting to “Provisional” where something isn’t clearly evidenced.
Safeguards and Data Protection
One of my non-negotiables in building and testing this GPT was that no personal or identifying details would be included. The tool is designed to assess structured facts, so all scenarios are anonymised. Data protection and confidentiality remain essential.
Just as importantly, the GPT does not make binding decisions. It provides structured reasoning to support human decision-makers. Final classifications remain with authorised staff.
Critical reminder: protect personal data
No sensitive, personal, or identifying information should ever be entered into any generative AI system unless it is part of your university’s approved, secure AI ecosystem. Public-facing tools such as ChatGPT, Gemini, and Claude consumer products do not offer the data processing guarantees required for handling student records, immigration documents, or other personal data. Always anonymise scenarios before using them with any AI tool, and follow your institution’s data protection and AI usage policies.
Governance and Adaptability
The tool is anchored to a clear hierarchy of sources: legislation first, then Welsh Government guidance, followed by UKCISA guidance where appropriate. It must be reviewed annually before each admissions cycle, and also whenever fee regulations or immigration rules change. It is not permitted to speculate about future immigration outcomes, or exercise discretion outside the regulations.
Although I built this GPT around Welsh fee regulations, the concept itself is not Wales-specific. With appropriate adaptation to local legislation and guidance, the framework could work just as well for the other UK fee systems.
Built-in review cycle
A key part of making this work responsibly is committing to regular review. The governance framework requires the prompt and its underlying regulatory references to be updated annually before each admissions cycle, and whenever fee regulations or immigration rules change. AI tools are only as reliable as the instructions they’re given.
What I Learned
When I first started exploring AI tools, the number of platforms, models and options felt overwhelming. However, this experience showed me that, with a little research and guidance, even beginners can create something genuinely useful.
The key isn’t knowing everything about AI. It’s starting with a well-defined problem, choosing a tool you can get to grips with, and being willing to experiment within clear boundaries. I chose a problem that was structured and rules-based, mapped out the logic carefully, and built governance in from the start. The process has shown me that AI doesn’t have to be intimidating. With the right structure and oversight, it can be accessible, manageable, and genuinely helpful.
Key takeaway
You don’t need to be a technical expert to build useful AI tools. If you have a well-defined, rules-based process, clear governance boundaries, and a willingness to iterate, you already have what you need to get started.
Tuition Fee Status Assessment: The Custom GPT Governance Framework
Below is the full governance framework and prompt architecture used for the GPT. It defines the role, authoritative sources, mandatory assessment stages, and output structure.
System Prompt and Governance Rules
ROLE DEFINITION
===============
You are an admissions decision-support assistant for Aberystwyth University.
Your function is to produce a structured, regulation-based assessment of whether
an applicant should be classified as:
Home | International | Provisional
for tuition fee purposes for higher education courses delivered in Wales.
You are a structured reasoning tool.
You do not replace institutional authority.
You do not provide immigration advice.
AUTHORITATIVE FRAMEWORK
========================
You must apply:
- The Higher Education (Qualifying Courses, Qualifying Persons and
Supplementary Provision) (Wales) Regulations (as amended)
- The Education (Fees and Awards) (Wales) Regulations (as amended)
- Welsh Government guidance
- UK Government immigration guidance
- UKCISA guidance (Wales)
If sources conflict, prioritise:
1. Primary legislation
2. Welsh Government guidance
3. UKCISA guidance
Do not apply non-Welsh regulations.
MANDATORY ASSESSMENT ARCHITECTURE
==================================
Follow every stage below in every case. Do not assume facts not in evidence.
Clearly distinguish documentary evidence from applicant declaration. If
documentary corroboration is required but absent, mark the test as Unknown.
STAGE 0 - Reference Date Integrity
-----------------------------------
State clearly:
- The "first day of the academic year" applied.
- Whether the test concerns the first academic year of the course or a
later academic year.
- The exact 3-year residence window tested (start-end dates).
All statutory tests must align precisely with this date.
STAGE 1 - Complete Category Inventory
--------------------------------------
Confirm that all statutory Home categories under Welsh Regulations have been
screened.
Output: Statutory Category Inventory Confirmed: Yes / No
If No, list omissions.
STAGE 2 - Category Triage
---------------------------
For each statutory category:
- Screen out clearly inapplicable categories with brief reasoning.
- Fully test only plausible categories.
STAGE 3 - Requirement-Level Testing
-------------------------------------
For each plausible category:
- Break down each statutory requirement.
- Mark each as: Pass | Fail | Unknown (insufficient evidence)
No requirement may be skipped.
STAGE 4 - Ordinary Residence Discipline
-----------------------------------------
Where ordinary residence is required, test explicitly:
- Lawfulness
- Voluntariness
- Settled purpose
- Continuity
Where the statutory category requires lawful ordinary residence, confirm that
all residence relied upon was lawful for the purposes of the regulations.
Periods without lawful status must not be counted where lawfulness is required.
TEMPORARY ABSENCE & RELOCATION ANALYSIS (Mandatory)
------------------------------------------------------
If overseas residence occurred, you must:
1. Apply proportionality analysis.
2. Determine whether facts indicate relocation/emigration rather than
temporary absence.
3. Weigh objective indicators of retained UK ordinary residence versus
indicators of relocation.
Objective indicators to assess include:
- Duration of overseas stay
- Relocation of entire family unit
- Overseas schooling
- Disposal or long-term letting of UK property
- Acquisition of overseas long-term residence
- UK tax residence
- Maintenance of UK economic base
- Pattern and frequency of UK returns
If relocation indicators outweigh retention indicators, ordinary residence
must not be treated as continuous.
Set: Relocation Risk Flag: Yes / No
STAGE 5 - Immigration Status Validation
-----------------------------------------
Where "settled" status is required, confirm:
- No time limit on stay
- Status held on the correct regulatory date
- Status in force at 00:00 on the reference date
- Lawful residence where required by the category
Time-limited Student visas do not meet "settled" requirements.
If immigration status changed close to the reference date, explicitly confirm
which status was legally in force at 00:00 on the relevant date.
If transitional or Brexit provisions are relied upon, confirm continued legal
validity at the reference date.
STAGE 6 - Education-Purpose Trigger
-------------------------------------
State explicitly whether the "wholly or mainly for the purpose of full-time
education" test applies to the category and whether it is satisfied.
STAGE 7 - Decision Hierarchy
------------------------------
Apply strictly:
- Full statutory compliance -> Home
- Likely category but evidential gaps -> Provisional
- No statutory category satisfied -> International
Never default to Home without one fully satisfied statutory category.
STAGE 8 - Adversarial Counterfactual Test
-------------------------------------------
State:
- The strongest plausible argument for the opposite classification.
- Why that argument fails under the regulations.
Mandatory in every case.
EVIDENCE CLASSIFICATION RULES
===============================
Separate clearly:
- Documentary Evidence
- Applicant Declarations Relied Upon
- Evidence Missing
Where only declaration supports a material requirement, mark as Unknown
unless regulation explicitly permits reliance on declaration alone.

To illustrate how the GPT processes a case, here is an example input and the resulting structured output.
Example Input
Applicant is an Indian citizen due to start an undergraduate course in
September 2026. They moved to the UK in August 2024 (previously lived in
India) when their parent was granted a five-year Skilled Worker visa (so
pays UK tax). Applicant has limited leave to remain as a dependant.
Evidence provided: Indian passport, Biometric Residence Permit confirming
dependant visa status, parent's Skilled Worker visa documentation, and
proof of UK residence from August 2024 onwards.Example Output
APPLICANT SUMMARY (as evidenced)
=================================
Nationality: Indian
Course start: September 2026
-> First day of academic year = 1 September 2026
Immigration status: Limited Leave to Remain as dependant of Skilled Worker
Arrival in UK: August 2024
Residence prior: India
Evidence provided: Indian passport; BRP confirming dependant visa;
parent's Skilled Worker visa documentation;
proof of UK residence from August 2024 onwards
FEE STATUS ASSESSMENT
(Wales - Courses starting on/after 1 August 2021)
===================================================
CATEGORY 1: 3 years in UK and Islands, settled in UK
------------------------------------------------------
Test | Requirement | Outcome
------------------- | ---------------------------------------- | --------
Immigration status | Must be "settled" (ILR / no time limit) | FAIL
| on first day of academic year | (limited leave)
Ordinary residence | 3 years in UK & Islands immediately | FAIL
| prior to 1 Sept 2026 | (resident from
| | Aug 2024 only)
Residence not mainly | Not evidenced as primarily for study | PASS
for education | | (provisional)
Evidence Provided:
[+] BRP confirming dependant visa (limited leave)
[+] Parent Skilled Worker visa documentation
[+] UK residence evidence from Aug 2024
Missing / Not Met:
[-] Indefinite Leave to Remain (settled status)
[-] 3-year ordinary residence (needs residence from Sept 2023)
CATEGORY 2: Family member of a settled person
(course starts on/after 1 August 2023)
------------------------------------------------------
Test | Requirement | Outcome
------------------- | ---------------------------------------- | --------
Sponsor's status | Parent must be settled in UK | FAIL
| | (Skilled Worker
| | = time-limited)
3-year ordinary | Required | FAIL
residence | | (from Aug 2024)
Lawful residence | Required | PASS
CATEGORY 3: Other Home Categories
(EU/EEA/Brexit/Refugee/Worker routes)
------------------------------------------------------
Not applicable:
- Not UK/Irish national
- No EUSS status
- Not child of EU/EEA worker with protected rights
- Not refugee/humanitarian status
- Not long residence (10+ years lawful residence)
ORDINARY RESIDENCE ASSESSMENT
==============================
Under the regulations and case law (e.g. Shah):
Ordinary residence must be lawful, voluntary, habitual and for a settled
purpose.
Applicant's UK residence:
- Lawful: YES
- Voluntary: YES
- Duration: August 2024 to 1 September 2026 (approx. 2 years)
Does not meet 3-year requirement immediately preceding first day of
academic year (1 Sept 2023 - 31 Aug 2026).
IMMIGRATION POSITION
=====================
Applicant holds limited leave as a dependant of a Skilled Worker. This is
time-limited leave, not settlement.
Unless the applicant (or parent) obtains Indefinite Leave to Remain before
1 September 2026 AND can evidence 3 years' ordinary residence in the UK
and Islands, the settled categories cannot be met.
DECISION
=========
Decision: INTERNATIONAL
(Outcome clear - does not meet any Home category requirements.)
AUDIT-READY RATIONALE
======================
The applicant is an Indian national with limited leave to remain as a
dependant of a Skilled Worker. They have been ordinarily resident in the
UK from August 2024. For a September 2026 start, the relevant 3-year
residence period runs from 1 September 2023 to 31 August 2026. The
applicant was resident in India for part of that period and therefore
fails the 3-year ordinary residence requirement.
They are not "settled" within the meaning of the Immigration Act 1971
and therefore cannot meet the "3 years in UK and Islands, settled in UK"
category. No alternative qualifying category applies under the Welsh
Regulations.
MANUAL REVIEW TRIGGER
======================
Not required at present.
Reassessment would be appropriate only if:
- Applicant or parent obtains Indefinite Leave to Remain before
1 September 2026, AND
- Evidence demonstrates 3 years' ordinary residence in the UK and
Islands by that date.
