In education, "alternative assessment" is in direct contrast to what is known as "traditional testing" "traditional assessment," or "standardized assessment." Instead of traditional selected-response or constructed-response tests that look for discrete facts or knowledge students recall in a standard way, students can apply knowledge in ...
Two-alternative forced choice (2AFC) is a method for measuring the sensitivity of a person or animal to some particular sensory input, stimulus, through that observer's pattern of choices and response times to two versions of the sensory input. For example, to determine a person's sensitivity to dim light, the observer would be presented with a ...
The Alternatives Research and Development Foundation (ARDF) provides grants to advance the use of non-animal methods in the fields of biomedical testing, research, and education. [ 89 ] The international NC3Rs 3Rs Prize is awarded to highlight an outstanding original contribution to scientific and technological advances in the 3Rs in medical ...
The Johns Hopkins University Center for Alternatives to Animal Testing (CAAT) has worked with scientists, since 1981, to find new methods to replace the use of laboratory animals in experiments, reduce the number of animals tested, and refine necessary tests to eliminate pain and distress (the Three Rs as described in Russell and Burch's Principles of Humane Experimental Technique).

The basic computer-adaptive testing method is an iterative algorithm with the following steps: [3] The pool of available items is searched for the optimal item, based on the current estimate of the examinee's ability; The chosen item is presented to the examinee, who then answers it correctly or incorrectly
In addition, even testing for known GMOs is time-consuming and costly, as current reliable detection methods can test for only one GMO at a time. Therefore, research programmes such as Co-Extra are developing improved and alternative testing methods, for example DNA microarrays.

An ABX test is a method of comparing two choices of sensory stimuli to identify detectable differences between them. A subject is presented with two known samples (sample A, the first reference, and sample B, the second reference) followed by one unknown sample X that is randomly selected from either A or B.
