Module grade_mapping 

Our grade in the study registry’s terms. A scale or grade the registry does not know is rejected at request level, taking the whole batch of twenty-five with it, so every pair that reaches a batch has been through map_grade or is_known_grade.

Structs

GradeSource

What the completion says and what the module and the chosen enrolment say the scale should be.

MappedGrade

Enums

GradeComparison

How a grade stands against one the registry already holds.

GradeScaleFamily

Constants

FAIL_GRADE_ID

MAX_NUMERIC_GRADE

NUMERIC_GRADE_SCALE_ID

PASS_FAIL_GRADE_SCALE_ID

TODO: Suotar has not confirmed the spelling. Both are accepted on the way in; this is the one we send.

PASS_FAIL_GRADE_SCALE_ID_ALT

The other accepted spelling of the same scale, which our own legacy pull path sends.

PASS_GRADE_ID

Functions

compare_grades

Whether candidate is worth pushing over registered, which is the frozen pair of an attempt the registry accepted.

grade_rank 🔒

Where a grade sits within its own scale. Comparable only against another rank of the same scale.

grade_scale_family

is_known_grade

Whether a frozen pair is one the registry will accept. Checked again before batching: an unknown pair is a request-level rejection, so one bad row would fail twenty-four good ones.

map_grade

Maps a completion into the scale the registry expects, preferring what it told us to a guess.

same_grade_scale

Whether two scale ids name the same scale. The pass/fail id has two spellings in circulation, so comparing the strings would call an attainment we ourselves registered a different scale.
