Explanations for some of the commonly used terms in job advertisements.

FTE means full-time equivalent.  For example, a job advertised as 0.5 FTE means that you will work half the amount of time that a person working full-time would do (where 1.0 represents full-time hours). 

Pro rata
Pro rata is used when a job is part-time and the salary quoted is what someone working full-time would receive for the same job. Your salary will be calculated according to what proportion of a full-time job your hours make up.  

Fixed term contract
You are employed for a fixed period of time and then your contract ends.

IFSTL (UK job advertisements)
Interest-Free Season Ticket Loan.  For example: Salary: £22,500 pa + IFSTL.
