The Nottingham system is also called the Bloom–Richardson–Elston system (BRE), [14] or the Elston-Ellis modification [15] of the Scarff-Bloom-Richardson grading system. [16] [17] It grades breast carcinomas by adding up scores for tubule formation, nuclear pleomorphism, and mitotic count, each of which is given 1 to 3 points.
The histologic appearance of cancer cells can be scored on these three parameters on a scale from one to three. The sum of these grades is a number between 3 and 9. The score is called a Bloom Richardson Grade (BR) and is expressed [sum of the grades]/9. For example, cells that were graded 2 on all three parameters would result in a BR score of ...
The grade score (numerical: G1 up to G4) increases with the lack of cellular differentiation - it reflects how much the tumor cells differ from the cells of the normal tissue they have originated from (see 'Categories' below). Tumors may be graded on four-tier, three-tier, or two-tier scales, depending on the institution and the tumor type.

The Nottingham prognostic index (NPI) is used to determine prognosis following surgery for breast cancer. [1] [2] Its value is calculated using three pathological criteria: the size of the tumour; the number of involved lymph nodes; and the grade of the tumour. [1]
Schools in Somerset County have listed their honor roll students for the first quarter, nine-weeks grading period. North Star. Highest honors (All A’s)
G (1–4): the grade of the cancer cells (i.e. they are "low grade" if they appear similar to normal cells, and "high grade" if they appear poorly differentiated) S (0–3): elevation of serum tumor markers; R (0–2): the completeness of the operation (resection-boundaries free of cancer cells or not) Pn (0–1): invasion into adjunct nerves
