Depend upon fields
The HESA session population is a count of all higher education and further education student instances active at a reporting higher education provider at any point in the reporting period 1 August to 31 July except:
1. dormant student instances (those who have suspended studying but have not formally de-registered)
2. incoming visiting and exchange student instances
3. postdoctoral student instances, and students primarily studying outside the UK
4. instances where the whole of the programme of study is outside of the UK
5. students on sabbatical
This derived field is created in both the Student record (Cyy051) and the Student Alternative record (Cyy054). The Student Alternative record makes use of fields from a rolled-up Instance_End analysis table which reflects the position of the student in the last active instance period.
As the Student Alternative record is collected for a smaller subset of those collected in the Student record, the Technical Specification is less complex and requires fewer exclusions.
HE levels are defined as first letter of Course.COURSEAIM = D, E, L, M, H, I, J, C.
FE levels are defined as first letter of Course.COURSEAIM = P, Q, R, S, X
Students studying primarily abroad are identified through their location of study (i.e. LOCSDY = 'S'). For the purposes of the Student record, Instance.EXCHANGE valid entries Y and Z are not used in determining location of study.
Please note: although records returned in the Student record as Instance.REDUCEDI = '08' ('Instances present on the Student Loans Company (SLC) attendance confirmation date who do not progress beyond two weeks of their course') may be derived to 1 in this field, the absence of data in Instance.STULOAD associated with such a record will result in any FTE calculation deriving to zero, and therefore their exclusion from most analysis.
Y1 is obtained by concatenating the first two digits from year in the system date with the first two digits of RECID, e.g. 01 for 2001/02.
