A concept inventory is a criterion-referenced test designed to help determine whether a student has an accurate working knowledge of a specific set of concepts. Historically, concept inventories have been in the form of multiple-choice tests in order to aid interpretability and facilitate administration in large classes. Unlike a typical, teacher-authored multiple-choice test, questions and response choices on concept inventories are the subject of extensive research. The aims of the research include ascertaining (a) the range of what individuals think a particular question is asking and (b) the most common responses to the questions. Concept inventories are evaluated to ensure test reliability and validity. In its final form, each question includes one correct answer and several distractors. Ideally, a score on a criterion-referenced test reflects the amount of content knowledge a student has mastered. Criterion-referenced tests differ from norm-referenced tests in that (in theory) the former is not used to compare an individual's score to the scores of the group. Ordinarily, the purpose of a criterion-referenced test is to ascertain whether a student mastered a predetermined amount of content knowledge; upon obtaining a test score that is at or above a cutoff score, the student can move on to study a body of content knowledge that follows next in a learning sequence. In general, item difficulty values ranging between 30% and 70% are best able to provide information about student understanding. The distractors are incorrect or irrelevant answers that are usually (but not always) based on students' commonly held misconceptions.〔"Development and Validation of Instruments to Measure Learning of Expert-Like Thinking." W. K. Adams & C. E. Wieman, 2010. International Journal of Science Education, 1-24. iFirst, 〕 Test developers often research student misconceptions by examining students' responses to open-ended essay questions and conducting "think-aloud" interviews with students. The distractors chosen by students help researchers understand student thinking and give instructors insights into students' prior knowledge (and, sometimes, firmly held beliefs). This foundation in research underlies instrument construction and design, and plays a role in helping educators obtain clues about students' ideas, scientific misconceptions, and didaskalogenic ("teacher-induced" or "teaching-induced") confusions and conceptual lacunae that interfere with learning. ==Concept inventories in use== Concept inventories are education-related diagnostic tests.〔completing introductory college physics courses ) could state Newton's Third Law at the beginning of the course. FCI data showed that less than 15% of them fully understood it at the end".These results have been replicated in a number of studies involving students at a range of institutions (see sources section below). That said, there remains questions as what exactly the FCI measures.〔Huffman, D. & P. Heller. 1995. What does the force concept inventory actually measure? The Physics Teacher 33: 138-143; Heller, P. & D. Huffman. 1995.()〕 Results from Hake (1998) using the FCI have led to greater recognition in the science education community of the importance of students' "interactive engagement" with the materials to be mastered.〔Hake, R. R. 1998. Interactive-engagement versus traditional methods: a six-thousand-student survey of mechanics test data for introductory physics courses. Am. J. Physics 66, 64-74.()〕 . Since the development of the FCI, other physics instruments have been developed. These include the Force and Motion Conceptual Evaluation developed by Thornton and Sokoloff〔Thornton RK, Sokoloff DR (1998) Assessing student learning of Newton's laws: The Force and Motion Conceptual Evaluation and Evaluation of Active Learning Laboratory and Lecture Curricula. . Amer J Physics 66: 338-352. ()〕 and the Brief Electricity and Magnetism Assessment developed by Ding et al.〔Ding, L, Chabay, R, Sherwood, B, & Beichner, R (2006).

Phys., 62, 750-762, (1994).〕 Information about physics concept tests can be found at the NC State Physics Education Research Group website (see the external links below).

An example of an inventory that assesses knowledge of such concepts is an instrument developed by Odom and Barrow (1995) to evaluate understanding of diffusion and osmosis.〔Odom AL, Barrow LH 1995 Development and application of a two-tier diagnostic test measuring college biology students' understanding of diffusion and osmosis after a course of instruction.
