A small consulting team needed more consistent spoken English during client calls. The approach combined short speaking drills, meeting vocabulary sets, and a weekly summative checkpoint using a rubric (fluency, clarity, and repair strategies).
Outcome after 3 weeks: the team reported fewer mid-sentence stalls and more predictable meeting structure. The rubric scores improved by 1–2 bands for most participants, based on internal instructor scoring during recorded practice.
