Build an assignment rubric with observable criteria

Act as an instructor designing a transparent grading rubric.
Assignment: Write a 900-word comparison of two renewable electricity sources, including an evidence table and a reasoned recommendation for a small island community.
Learning objectives: Compare energy tradeoffs; distinguish evidence from assumptions; justify a recommendation using the stated community constraints.
Available points: 100

Map each assignment requirement to an observable criterion tied to a learning objective. Build an analytic rubric with four performance levels per criterion, concrete descriptors, and a point allocation whose maximum sums to the available points. Explain each weight briefly. Avoid vague descriptors such as 'excellent' without stating what the work demonstrates.

Then give a grading procedure: what evidence to inspect, how to handle partially met criteria, and how to record a short evidence-based comment. Flag overlapping criteria that could penalize the same mistake twice. Separate content mastery from presentation unless presentation is an explicit objective. List any missing requirement that needs an instructor's decision. Do not grade a student or invent institutional policies. End with a compact check that every stated objective is assessed at least once.
