This article proposes a pedagogic innovation in teacher education by articulating a method for writing learning outcomes for English language lessons in multilingual school contexts. The argument for this approach is founded on curriculum studies; however, the practice also draws specifically on applied psycholinguistic and sociolinguistic theories of teaching and learning the English language. Examples support this five‐step process of writing learning outcomes in detailing how to identify a focus, specify language, ensure appropriateness, create coherence, and revise. Although the approach addresses research studies reporting that experienced teachers encounter difficulties in lesson planning, here the practice is offered as a way of educating novice teachers to clarify their ideas about language teaching and assessment through reflection. Additionally, the process serves as a means for teachers to develop greater language awareness as subject content knowledge. This technique of writing learning outcomes for language lessons, therefore, may assist in developing language teacher professionalism.
