The Lunar Phases Concept Inventory (LPCI) was developed to aid instructors in assessing students' mental models of lunar phases.  Based upon an in-depth qualitative investigation of students' initial models of lunar phases, this multiple-choice inventory was designed to take advantage of the innovative model analysis theory to probe the different dimensions of students' mental models of lunar phases. The development of this inventory will be discussed, as well as the processes involved in establishing its reliability and validity.
