pMLU is a relational-analysis metric used alongside PCC.

• A. PCC
• B. Independent Analysis
• C. pMLU
• D. Phonotactic Probability

Answer: (C)

Measuring phonological development often combines an accuracy metric with a relational-analysis metric. pMLU serves as that relational index when used alongside the Percent Consonants Correct measure. It goes beyond counting how many consonants a child produces correctly by evaluating how the child's utterances align with the target phonology, capturing patterns of substitutions, deletions, and overall structural organization within utterances. This relational view helps reveal whether a child is maintaining the phonological relationships that define the target language, not just hitting individual sounds. PCC tells you the proportion of consonants correct, but it doesn't show the structure of the productions. Using pMLU with PCC gives a fuller picture of development: accuracy plus phonological structure. The other options don’t fit because Independent Analysis isn’t a standard paired metric, and Phonotactic Probability concerns how likely a sequence is in the language rather than how well the child’s utterances reflect target phonology.
