The first step in validating a criterion-referenced test is to estab-lish item-objective congruence. It answers the question: How welldoes the item measure the objective? Match each item to an ob-jective, and assess how well the item measures the performancestated in the objective.
A basic assumption made by ScorePak® is that the test under analysis is composed of items measuring a single subject area or underlying ability. The quality of the test as a whole is assessed by estimating its “internal consistency.” The quality of individual items is assessed by comparing students’ item responses to their total test scores.
Item analysis is the act of analyzing student responses to individual exam questions with the intention of evaluating exam quality. It is an important tool to uphold test effectiveness and fairness. Item analysis is likely something educators do both consciously and unconsciously on a regular basis. In fact, grading literally involves studying ...

Basic Concepts in Item and Test Analysis. Susan Matlock-Hetzel. Texas A&M University, January 1997. Abstract. When norm-referenced tests are developed for instructional purposes, to assess the effects of educational programs, or for educational research purposes, it can be very important to conduct item and test analyses.
Evaluation is indispensable part of and different types of tests are used for assessment and consequently evaluation. Tests play important role in giving feedback stakeholders in education on various aspects therefore quality of tests has always been a hot issue since long; consequently literature is full of comprehensive discussion on validity, reliability and the characteristics of quality ...
A frequent challenge for nursing faculty is to write a test that effectively evaluates learning and prepares students to be successful on the NCLEX-RN examination. Use of item analysis is an approach often used to provide an objective evaluation of examinations. Interpreting these analyses, however, …
This is the question number taken from the student answer sheet, and the ScorePak® Key Sheet. Up to 150 items can be scored on the Standard Answer Sheet.
A basic assumption made by ScorePak® is that the test under analysis is composed of items measuring a single subject area or underlying ability. The quality of the test as a whole is assessed by estimating its “internal consistency.” The quality of individual items is assessed by comparing students’ item responses to their total test scores.
The item discrimination index provided by ScorePak® is a Pearson Product Moment correlation 2 between student responses to a particular item and total scores on all other items on the test. This index is the equivalent of a point-biserial coefficient in this application. It provides an estimate of the degree to which an individual item is measuring the same thing as the rest of the items.
Item analysis is a process which examines student responses to individual test items (questions) in order to assess the quality of those items and of the test as a whole. Item analysis is especially valuable in improving items which will be used again in later tests, but it can also be used to eliminate ambiguous or misleading items in a single test administration. In addition, item analysis is valuable for increasing instructors’ skills in test construction, and identifying specific areas of course content which need greater emphasis or clarity. Separate item analyses can be requested for each raw score 1 created during a given ScorePak® run.
A general rule of thumb to predict the amount of change which can be expected in individual test scores is to multiply the standard error of measurement by 1.5. Only rarely would one expect a student’s score to increase or decrease by more than that amount between two such similar tests. The smaller the standard error of measurement, the more accurate the measurement provided by the test.
ScorePak® arbitrarily classifies item difficulty as “easy” if the index is 85% or above; “moderate” if it is between 51 and 84%; and “hard” if it is 50% or below.
Suggests need for revision of test, unless it is quite short (ten or fewer items). The test definitely needs to be supplemented by other measures (e.g., more tests) for grading.
In doing so, item analysis can increase the efficacy of your exams by testing knowledge accurately. And knowing exactly what it is students know and what they don’t know, helps both student learning and instructor efficacy.
Item analysis should bring to light both questions and answers as you revise or omit items from your test.

It is an important tool to uphold test effectiveness and fairness.
Assessment via midterms, tests, quizzes, and exams is the way in which educators gain insight into student learning; in fact, assessment accounts for well over 50% of a student’s grade in many higher education courses.
Not only can item analysis drive exam design, but it can also inform course content and curriculum.
For validity measures that are based on statistics (i.e., Construct and Criterion Measures), list the specific numbers used to quantify validity. If the correlation between your test and another test that measures the same trait is .90, then list this number in your paper. For validity measures that are not based on statistics (e.g., face validity and some types of construct validity), make sure you include enough detail in your description so that the reader is convinced the test is reliable. Merely stating, for example, that experts believe the test has face validity will not convince the reader that will grade your paper.
Describe the type of reliability measure you use in the paper. If it is a test-retest reliability estimate, state that it is test-retest reliability. If it is a coefficient alpha, state that it’s coefficient alpha. List the specific number used to quantify the reliability. If the test-reliability estimate is .80, then state this number in your paper.
If you merely state that the test is “reliable” or that it “meets accepted standards of reliability” you will lose points. Describe the type of reliability measure you use in the paper. If it is a test-retest reliability estimate, state that it is test-retest reliability.
Information from the textbook. If the textbook contains an interesting fact, you must track down the original article the textbook is summarizing. You can read and cite articles that are referenced in the textbook. In fact, this is an excellent way to find articles.
Evaluating a Psychological Test Research Paper. 1. Title page. Include the title, your name, student ID, and date paper is submitted, and course and section number of the course. 2. Abstract. Your abstract should be a single paragraph on a separate page that briefly summarizes the main points of your paper.
If you use the EBSCO databases provided , you can check a box that will restrict the search to peer reviewed articles. If you have questions on whether a specific journal is acceptable, e mail the name of the journal and the name of the article to the instructor of this course.
Depending on the test you select, you may be able to include multiple measures of reliability in this section. For example, you might find both test-retest and coefficient alpha estimates that you can describe and list. But you must include at least ONE reliability measure in this section.
An important input to the supplier selection process are the guidelines for the types of suppliers you want. These guidelines are impacted by your Sourcing Strategy; which we will explore in another article.
The first step in the supplier selection process is to create a supplier selection scorecard. The supplier selection scorecard contains all the important elements you require in a supplier. It has long been stated, “That which does not get measured, does not get done”. Your scorecard should be quantifiable and include: Supplier characteristics.
Past suppliers – Depending upon the reasons why they are ‘past’ and not ‘current’. Competitors – You may be in a position to buy from a competitor if it is ethical and low-risk. Industry groups – many of which are non-profit and maintain data bases of member companies.
If all that work did not identify a clear winner, you may need to review your criteria and/or expand your search.
Depending on the critical good or service, you may negotiate with just the top supplier on your scorecard, even if others remain on the list of potentials. These others, of course, are not told they are not #1 until after you have completed negotiations and agreements are completed.
