Computerized adaptive testing is an AI-based approach to assessment where the test is personalized based on your performance as you take the test, making the test shorter, more accurate, more secure, more engaging, and fairer. If you do well, the items get more difficult, and if you do poorly, the items get easier. If an […]
Online proctoring software refers to platforms that proctor educational or professional assessments (exams or tests) when the proctor is not in the same room as the examinee. This means that it is done with a video stream or recording using a webcam and sometimes an additional device, which are monitored by a human and/or AI. […]
A Certification Management System (CMS) or Credential Management System plays a pivotal role in streamlining the key processes surrounding the certification or credentialing of people, namely that they have certain knowledge or skills in a profession. It helps with ensuring compliance, reducing business operation costs, and maximizing the value of certifications. In this article, we […]
ANSI ISO/IEC 17024 accreditation is an internationally recognized standard for the accreditation of personnel certification bodies. That is, it is a stamp of approval from an independent audit which says your certification is good quality. ANSI stands for the American National Standards Institute, while ISO refers to the International Organization for Standardization. The portion of […]
Microcredentials are short, focused, and targeted educational or assessment-based certificate programs that offer learners a way to acquire specific skills or knowledge in a particular field. In today’s fast-paced and rapidly evolving job market, traditional degrees may not always be enough to stand out among the competition, and they often take too long to achieve. […]
Automated essay scoring (AES) is an important application of machine learning and artificial intelligence to the field of psychometrics and assessment. In fact, it’s been around far longer than “machine learning” and “artificial intelligence” have been buzzwords in the general public! The field of psychometrics has been doing such groundbreaking work for decades. So how […]
Coefficient alpha reliability, sometimes called Cronbach’s alpha, is a statistical index that is used to evaluate the internal consistency or reliability of an assessment. That is, it quantifies how consistent we can expect scores to be, by analyzing the item statistics. A high value indicates that the test is of high reliability, and a low […]
Differential item functioning (DIF) is a term in psychometrics for the statistical analysis of assessment data to determine if items are performing in a biased manner against some group of examinees. This analysis is often complemented by item fit analysis, which ensures that each item aligns appropriately with the theoretical model and functions uniformly across […]
What is the difference between the terms dichotomous and polytomous in psychometrics? Well, these terms represent two subcategories within item response theory (IRT) which is the dominant psychometric paradigm for constructing, scoring and analyzing assessments. Virtually all large-scale assessments utilize IRT because of its well-documented advantages. In many cases, however, it is referred to as […]
A test security plan (TSP) is a document that lays out how an assessment organization address security of its intellectual property, to protect the validity of the exam scores. If a test is compromised, the scores become meaningless, so security is obviously important. The test security plan helps an organization anticipate test security issues, establish […]
