The calculation LEA's use is slightly different for HND/FD/DipHE -> Degree courses. The calculation is based mainly on the new degree course. There's a few stages to the workings, which I'll outline below:
Step 1 - Determine the standard full duration of the proposed first degree course, which means how long would the degree normally last if you weren't given direct entry. We'll call this number A.
Step 2 - Determine the standard full duration of the previous HND/HNC/DipHE/FD course (preliminary course). These are usually 2 years. Whatever yours turns out to be, we'll call it B for the bit of the workings.
Step 3 - Years spent on preliminary course. This is the length of time it took you to complete the previous course, not including any academic years that you may have had to repeat for compelling personal reasons. It will also take into account any previous higher education study you have undertaken. We will call this C, for a bit of continuity.
Now comes the formula, which I'll express as (X + Y) - C = Standard Entitlement.
X is equal to A or 3, whichever is greater.
If B is less than 3, then Y = 1. If it's greater than 3, then Y = 2.
Put your own numbers into that to give you your standard entitlement, and then allocate the entitlement from the final year of your degree course working backwards until it is all used up. Any years that you cannot allocate entitlement to will mean you cannot get fee support for that year of the course.
