Offer Details (OD)

The Offer Details File comprises data records for all offers and responses to offers for admission to a higher education undergraduate award course made through a Tertiary Admission Centre (TAC) or directly by a Higher Education Provider (HEP).

The data reported in the records of the Offers Details File provides information on the offers made in response to an applicant’s preferences (e.g. field of education, preference ordinal position) as at the Reference Date.

Data records are included for offers to all current preferences. The preference ordinal position of the offer record is that of the preference in the current set of preferences as at the Reference Date.

Each unique value for Element 700 (Application identification code) may have zero, one or multiple records in the Offer Details File as each offer recorded is reported as a separate data record.

The number of records linked to each unique value for Element 700 (Application identification code) will depend on:

  • If an offer is made to an applicant;
  • The number of offers made to an applicant; and
  • The administrative practices related to recording offers.


The Offer Details File is one of three files included in the Applications Details Submission. Other files included are the Applications Details (AD) file and Preference Details (PD) File.

Timing of these submissions is detailed in the Timing Matrix for the relevant reporting year which is available on the Data Requirements page.


The Offer Details data element specification document provides the complete set of elements that are to be reported.

In recognition that there are variations in the administrative process of institutions, some fields are discretionary despite being of key interest for the Department. Discretionary elements should have values reported unless data is not collected under current administrative processes. For mandatory elements, generic or ‘no information’ values should be submitted in exceptional cases only.

For data submissions through HEPCAT please refer to Offer Details File – Structure document for the relevant reporting year on HEIMSHELP.

For data submissions via web services please refer to the Application and Offers Technical Specifications.
