Write clear learning objectives

I need clear learning objectives for a three-week module on soil health for extension trainees. Write five measurable objectives that specify observable behavior and a performance threshold, then send them to Lydia in Training and copy the course instructor, Asha, for approval by Friday.

Before I present these objectives to Asha, make them easy to approve: start each with a student action verb, include the evidence I will collect, and show the pass/fail criterion for each objective so Asha can quickly see how we'll grade mastery.

I wrote ‘‘understand sustainable practices’’ and Asha pushed back that it’s not testable. I’m stuck on what concrete behavior shows understanding in a day‑long field session. What precise objective and assessment would you suggest for a trainee to demonstrate practical knowledge of soil compaction in a hands‑on workshop?

Over several courses I keep rewriting objectives after instructors complain they're not measurable. It wastes prep time and confuses learners. Which change in how I draft objectives would cut revision cycles, what template or checklist will force measurability, and how do I train instructors to accept the first draft as assessment‑ready?
