The '''Joint Academic Coding System''' (JACS) system iswas used by the [[Higher Education Statistics Agency]] (HESA) and the [[Universities and Colleges Admissions Service]] (UCAS) in the [[United Kingdom]] to classify academic subjects. It was replaced by the Higher Education Classification of Subjects (HECoS) and the Common Aggregation Hierarchy (CAH) for the 2019/20 academic year.<ref name=farewell>{{cite web|url=https://www.hesa.ac.uk/blog/28-04-2017/farewell-jacs-and-hello-hecos|title=Farewell to JACS, and hello to HECoS|publisher=HESA|date=27 April 2017|accessdate=10 May 2017}}</ref>

A JACS code for a single subject consists of a letter and three numbers. The letter represents the broad subject classification, e.g. F for physical sciences. The first number represents the principal subject area, e.g. F3 for physics, and subsequent numbers represent further details, similar to the [[Dewey Decimal Classification|Dewey Decimal System]]. ForThe principal subject of physics, for example, Fis representsbroken theinto 19 Physicaldetailed Sciencessubjects, represented by a letter plus three numbers: e.g., F300 Physicsrepresents physics, F330 Environmentalenvironmental Physicsphysics, and F331 Atmosphericatmospheric Physicsphysics.

==History==

HESA and UCAS used to operate two different (though similar) subject coding systems - HESAcode and Standard Classification of Academic Subjects (SCAS) respectively. In 1996 a joint project was launched to bring these two systemsystems together to create a unified structure. A project team was established with two people from each of the two organisationsorganizations. The project team became known as JACS since this was an acronym of their names (Jonathan Waller and Andy Youell from HESA, Clive Sillence and Sara Goodwins from UCAS).<ref name=farewell/>

The first operational version (v1.7) of the Joint Academic Coding System (retaining the JACS acronym) was published in 1999 and became operational in UCAS and HESA systems for the year 2002/03.

An update exercise took place in 2005 and JACS version 2 was introduced for the academic year 2007/08. JACS3JACS 3 was introduced for the 2012/13 year.

==JACS Codes in the UCAS system==

Course codes in the UCAS system are assigned by course providers and do not necessarily correspond to the JACS codes of the course subject.<ref>{{cite web|url=https://www.ucas.com/file/36576/download%3Ftoken%3DwKnv0Ur_|title=Full list of the current variables|publisher=UCAS|date=November 2016|quote=Please note: the course code is assigned to each course by the host provider and does not necessarily relate to JACS subject codes.|accessdate=10 May 2017}}{{Dead link|date=March 2019 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> UCAS course codes are four characters in length but, unlike JACS codes, may consist of any combination of letters and numbers in any order. However, historically UCAS created course codes from the JACS subject code, and many institutions continue to do this, which can lead to confusion between the two concepts.<ref>{{cite web|url=https://www.hediip.ac.uk/wp-content/uploads/JACS_Report_2013-07.pdf|title=Classifying subject of study: A roadmap to a new Joint Academic Coding System| date=July 2013|publisher=Higher Education Data and Information Improvement Programme|accessdate=10 May 2017|page=29}}</ref>

UCAS creates course codes based on the JACS codes of the course subject. In many cases the UCAS course code will be the same as the JACS subject code and this can lead to confusion between the two concepts.

Where a course involves more than one subject the, UCAS historically created the course code is based on an aggregation of the JACS codes. For courses whichthat are split 50:50 between two subjects, a code with two letters and two numbers is used, which combines the simplestprincipal (highest level)subject codes whichthat would be used for the two subjects if studied as individual degrees.<ref>{{cite web|archive-url=https://web.archive.org/web/20101220214158/https://www.ucas.com/he_staff/courses/jacs/codingprinciples|archive-date=20 December 2010|url=https://www.ucas.com/he_staff/courses/jacs/codingprinciple|publisher=UCAS|title=Course coding principles|accessdate=10 May 2017|url-status=dead}}</ref>

===Example===

Consider the BSc course '''Mathematics and Physics''':

*The simplestprincipal subject code for Mathematics iswas G100'''G1''', and the simplestprincipal subject code for Physics is F300'''F3'''.

*The combined codes used were '''GF13'''<ref>{{cite web|url=https://digital.ucas.com/courses/details?coursePrimaryId=971ecf84-8baf-0c4e-9e6c-86af084bca98&courseOptionId=42a85295-0a17-343c-680a-6eda9fe5f58a|title=Mathematics and Physics – University of Edinburgh|publisher=UCAS|accessdate=9 May 2017}}{{Dead link|date=March 2019 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> and '''FG31'''.<ref>{{cite web|url=https://digital.ucas.com/courses/details?coursePrimaryId=fc9d5b6d-0a2d-9475-b3b8-7fd46cb95966&courseOptionId=d643d300-cacf-39b7-7655-f0698b0fc757|title=Mathematics and Physics – University of Manchester|publisher=UCAS|accessdate=10 May 2017}}{{Dead link|date=March 2019 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

*The combined code uses '''G1''' for Mathematics, and '''F3''' for Physics.

*The codes '''GFD3''', '''GF1H''' and '''GFH1''' were also used.<ref>{{cite web|url=https://digital.ucas.com/courses/details?coursePrimaryId=2717f1c0-6716-2247-6427-bd91cce346d3&courseOptionId=2715730a-7cc2-8b9c-7ec1-a93e89e9dd7b|title=Mathematics and Physics – University of Bristol|publisher=UCAS|accessdate=10 May 2017}}{{Dead link|date=February 2020 |bot=InternetArchiveBot |fix-attempted=yes }}</ref><ref>{{cite web|url=https://digital.ucas.com/courses/details?coursePrimaryId=7de40e6d-6e82-ee6c-b270-89d7f4a91016&courseOptionId=549a2e3e-b1ab-f49d-780a-7928b0c2b5c2|title=Mathematics and Physics – University of Surrey|publisher=UCAS|accessdate=10 May 2017}}{{Dead link|date=March 2019 |bot=InternetArchiveBot |fix-attempted=yes }}</ref><ref>{{cite web|url=https://digital.ucas.com/courses/details?coursePrimaryId=7c8421b9-c8f2-c7fc-f16e-332f11b96dae&courseOptionId=7902fe7d-93b7-80b4-46bf-96385ab31d3b|title=Mathematics and Physics – University of Surrey (sandwich)|publisher=UCAS|accessdate=10 May 2017}}{{Dead link|date=March 2019 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

*The combined code is '''GF13''' because the letters always precede the numbers.

Another example was '''Music and Philosophy'''. The principal subject codes were '''W3''' (Music) and '''V5''' (Philosophy). The combined codes used are '''WV35'''<ref>{{cite web|url=https://digital.ucas.com/courses/details?coursePrimaryId=4cda0d62-c344-54ff-4366-6923d47a1c16&courseOptionId=d1355c12-0f5c-0226-bccb-960dd320e0ec|title=Music and Philosophy – University of Nottingham|publisher=UCAS|accessdate=10 May 2017}}</ref> or '''VW35''',<ref>{{cite web|url=https://digital.ucas.com/courses/details?coursePrimaryId=e36cff50-021c-36d0-e37a-4131d3ce26ad&courseOptionId=4f560230-1ba8-9164-05e7-b642636809a2|title=Music and Philosophy – University of Sheffield |publisher=UCAS|accessdate=10 May 2017}}</ref> while '''WV53''',<ref>{{cite web|url=https://digital.ucas.com/courses/details?coursePrimaryId=ba5c79da-fe87-a452-7220-8a1d5dd10b07&courseOptionId=446cc56a-7a90-ee90-ffd2-7069e1f4d695|title=Music and Philosophy – Durham University|publisher=UCAS|accessdate=9 May 2017}}{{Dead link|date=March 2019 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> was also used.

Another example is '''Music and Philosophy'''. The codes are W300 (Music) and V500 (Philosophy). The combined code is VW53 (also represents "Philosophy and Music"). Although it could theoretically be WV53, the letters are placed in alphabetical order by convention, and the numbers are placed in the same order following the subjects.

The same letter cancould be used twice (if the two subjects arewere within the same general subject area), such as GG41'''FF53''' for Computer Science'''Astronomy and MathematicsPhysics'''.<ref>{{cite web|url=https://digital.ucas.com/courses/details?coursePrimaryId=da6c889b-6c5d-7cb8-734e-ccd169d6f63a&courseOptionId=e71c28df-bce5-5dd0-5703-0b3850ef8c1c|title=Astronomy and Physics – University of Glasgow|publisher=UCAS|accessdate=9 May 2017}}</ref>

===Courses with major/minor subjects===

Coding iswas done differently for courses such as "Mathematics '''with''' Physics", which is not the same as "Mathematics '''and''' Physics".

The format for such courses iswas Y1Z9 where:

*Y100Y1 is the "major" subject which represents most of the degree course

*Z900Z9 is the "minor" subject which represents less of the course.

For example, Mathematics with Physics would be represented by G1F3, but Physics with Mathematics would be represented by F3G1. Hence the order in which the two subjects are notated iswas important historically.
