Morphology

chance-half + correlation

The parts 'chance' (random), 'half' (a part) and 'correlation' (a statistical relationship) do allow a reader to infer this refers to a correlation between randomly formed halves of a test. However, 'chance-half' is a specialized, hyphenated technical coinage and the precise statistical meaning and usage would not be fully predictable to a B1 learner without subject knowledge, so the transparency is partial.

Etymology

Chance-half correlation comes from a simple test trick: you split a test by chance into two halves and measure how similar students' scores are. If the two halves give similar scores, the correlation is high, so the test shows good 'reliability'.
