To view/assign candidate numbers and UCIs navigate to **Curriculum \> Exams \> Exam Candidates.** Exam candidates are displayed by year group. From this page, you can sort the data by any of the columns.  You can also download the displayed list as a .CSV file.  Selecting a year group and searching for a name will return results just for the selected year.  Selecting **All** in the year group list and searching for a name will return results from all year groups.   ![](https://supporttest.go4schools.com/hs-fs/hubfs/undefined-Apr-10-2026-08-53-18-9816-AM.png?width=1705&height=526&name=undefined-Apr-10-2026-08-53-18-9816-AM.png)   #### **Assigning candidate numbers** To assign candidate numbers, select the candidate(s) and click on the **Assign UCI & candidate numbers** option.  Candidate numbers will be assigned in the order the students are displayed, i.e. if you would like them assigned in alphabetical order, sort the candidates by the Last name column.  If you have candidates in a year group who already have numbers but others who don’t, e.g. students have joined your sixth form from other schools, GO will automatically skip over students who have already got a candidate number, meaning you can select the whole year group, if easier. ![](https://supporttest.go4schools.com/hs-fs/hubfs/undefined-Apr-10-2026-08-53-19-4396-AM.png?width=1697&height=620&name=undefined-Apr-10-2026-08-53-19-4396-AM.png)   Using the toggles, select to **Assign candidate numbers** and/or UCI and enter the start number, if applicable.  UCIs can only be assigned if the Centre number is present.  If this field is blank, please raise a Support ticket.  Schools with multiple Centre numbers should select the relevant number from the dropdown list. ![](https://supporttest.go4schools.com/hs-fs/hubfs/undefined-Apr-10-2026-08-53-20-1915-AM.png?width=1128&height=808&name=undefined-Apr-10-2026-08-53-20-1915-AM.png) The Board identifier will normally be zero for UK-based centres.  International centres should change the Board identifier to the correct letter.  More information can be viewed by hovering over the i icon: ![](https://supporttest.go4schools.com/hs-fs/hubfs/undefined-Apr-10-2026-08-53-20-5202-AM.png?width=309&height=327&name=undefined-Apr-10-2026-08-53-20-5202-AM.png) #### **Entering existing UCIs** To enter an existing UCI for a candidate, click on the **Edit UCI** button.  GO will validate the UCI and flag any errors.  Should the UCI be invalid, please check with the student’s previous school.   ![](https://supporttest.go4schools.com/hs-fs/hubfs/undefined-Apr-10-2026-08-53-19-2404-AM.png?width=1469&height=102&name=undefined-Apr-10-2026-08-53-19-2404-AM.png)   Existing UCIs can also be uploaded using a .CSV file.   Without selecting any students, click on the Assign UCI & candidate numbers link, then select the UCI CSV import tab.  ![](https://supporttest.go4schools.com/hs-fs/hubfs/undefined-Apr-10-2026-08-53-20-7541-AM.png?width=1446&height=849&name=undefined-Apr-10-2026-08-53-20-7541-AM.png) Your file should be formatted in one of the following two ways:   ![A white paper with black text Description automatically generated](https://supporttest.go4schools.com/hs-fs/hubfs/undefined-Apr-10-2026-08-53-19-7192-AM.png?width=1130&height=234&name=undefined-Apr-10-2026-08-53-19-7192-AM.png) UCIs will be validated before being uploaded.   #### **Releasing candidate numbers** Candidate numbers can be released once candidates are marked as Leavers.  From the Exam candidates screen, select **Release leaver candidate numbers**. ![A white background with black border Description automatically generated](https://supporttest.go4schools.com/hs-fs/hubfs/undefined-Apr-10-2026-08-53-19-9476-AM.png?width=1909&height=246&name=undefined-Apr-10-2026-08-53-19-9476-AM.png)   Select the relevant academic year and year group and GO 4 Schools will display the number of candidate numbers being released, together with the first and last number.  Click on **Release** to complete the process.  These candidate numbers will now be available when you next complete the Assign process. ![A screenshot of a computer Description automatically generated](https://supporttest.go4schools.com/hs-fs/hubfs/undefined-Apr-10-2026-08-53-21-4221-AM.png?width=489&height=399&name=undefined-Apr-10-2026-08-53-21-4221-AM.png) -
