Who is involved in the test’s development?

Test specialists, test reviewers, editors, teachers, and specialists in the subject or skill being tested are the professionals involved in developing ETS test items. Each question is reviewed multiple times by multiple professionals to obtain a high-quality item.

How does ETS develop tests and test questions?

Before ETS can develop a test, it goes through a complex process first. There are seven steps followed in developing tests and test questions. These are the following steps necessary in the testing industry to meet the highest standards for quality and fairness.

  • Identifying Objectives. Before anything else, ETS appoints dozens of professionals, including educators, professional associations, and licensing boards, to identify a need to develop a test. Once agreed, a test will be developed after answering the following questions:
  • Who will take the test and for what purpose?
  • What skills and/or areas of knowledge should be tested?
  • How should test takers be able to use their knowledge?
  • What kinds of questions should be included? How many of each kind?
  • How long should the test be?
  • How difficult should the test be?
  • Item Development Committees

After answering the questions, it is time to appoint item development committees. Their responsibilities include defining the objective and specifications of the test, making sure that the test items are unbiased, and deciding on the test format. The test format may be multiple-choice, constructed-response, computer-delivered, paper-based, essay, etc. Other responsibilities include examining supplemental test materials, reviewing test items written by ETS staff, and writing the test items.

  • Writing and Reviewing Questions. Two of the responsibilities of the item development committees are to write and review test questions. These test questions are reviewed and revised multiple times to make sure that there are no test errors. Possible errors include the questions not being concise, having more than one possible answer in the choices, and not conforming to the test format. In this step, the making of a scoring guide is also done. Scoring guides are used for subjective questions like essays, short written answers, and oral responses. This is to ensure that the scores will be accurate across test takers.
  • The Pretest. Now, it is time for the pilot testing. It is the process when the test questions are administered to a sample group. Take note that the sample group must meet the characteristics of the population for whom the test is intended. Sample characteristics are age, socioeconomic status, field of study, interests, career, etc. This step enables test developers to determine the difficulty of test questions and identify ambiguity. Then, more revisions will be made based on the obtained results. There may be questions and choices that need to be revised or eliminated.
  • Detecting and removing unfair questions. Standardized tests must be fair. In this step, tests must meet guidelines set by trained reviewers. Here, it must be proven that the test, test items, and others are not inappropriate. There shouldn’t be language, content, symbols, phrases, or words that are sexist, racist, or offensive. It is done through a thorough review as well as through statistics. This is a very important step for ETS because it is devoted to producing tests that would advance quality and equity in education for people worldwide.
  • Assembling the Test. Following the test’s assembly, it is reviewed by other specialists, committee members, and, in some cases, outside experts. Each reviewer independently answers all questions and gives a list of correct responses to the test developers. The lists are compared to the ETS answer keys to ensure that the desired answer is the correct answer. Before the exam is published, any discrepancies are rectified.
  • Make certain that the test questions function properly even after the test has been administered. The test development does not end after the assembly. The statisticians and test developers ensure that the tests are working as predetermined. Every question undergoes preliminary statistical analysis. If a problem is discovered, corrective action is taken before final scoring and score reporting.

ETS goes through all of these steps in developing a test to ensure a fair, valid, and reliable test. Time, hard work, and rigorous reviews – are all devoted by assessment specialists developing these standardized tests.
