AMPR is a scoring system designed for young writers of non-rhotic varieties of English such as English Received Pronunciation. It is a non-exhaustive scheme, meant to be run with the Insertion penalty to 0. The stimuli are allophonic IPA transcriptions, as discussed in more detail below.

AMPR scoring operates to a certain extent on the allophonic level. The following transcriptional conventions are assumed:
