Attached is a sample item analysis that shows the summary table of statistics for all items (questions) for a pilot assessment of a memory test. The memory test presents a short video depicting a law enforcement scenario and requires candidates to recall relevant details. The test is comprised of 10 multiple choice questions with four options (A-D). For the sample of 10 items, the correct answer is “A”. Review the item difficulty (P), discrimination [R(IT)], and the distractors (options B-D). Item Analysis Interpretation Discussion

- Which item(s) could you remove altogether from the exam? Why?
- Which distractor(s) would you revise? Why?
- Which items are working well? Why?
- What next steps in test development would you recommend?

You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.
Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.
Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.
The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
