The construct of "learning potential" has been proposed to capture differences between learner independent performance and performance during Dynamic Assessment (DA). This paper introduces a new LPS formula implemented in a DA study involving Pakistani learners of L2 Chinese. Learners were randomly assigned to a control or experimental group and administered a pre-, post-, and more difficult transfer test, each focused on verb-resultative constructions. Use of the new learning potential score (LPS) formula allowed for greater differentiation of learner trajectories.
