van der Linden in his chapter, is the dependence of examinee scores on test dif culty Quite simply, examinees obtain lower scores on dif cult tests, and higher scores on easy tests Needed is a psychometric model that adjusts scores for test dif culty and makes scores invariant or independent of the choice of test items Within the framework of classical test theory is the well developed topic of score equating (see Gulliksen, 1950; Kolen & Brennan, 1995) but it is not feasible to use classical test score equating when each examinee receives a unique set of items, as is the case in computer-adaptive testing There are many testing situations where the use of non-equivalent tests to examinees may be of interest For example, more effective administration of aptitude tests, personality tests, and quality of life tests is possible with computer-adaptive tests described in the van der Linden chapter Testing time can be cut at least in half by adapting a test to the examinee (see, for example, Mills, Potenza, Fremer, & Ward, 2002; van der Linden & Glas, 2000; Wainer et al, 2000) Assessment begins at a level of dif culty based on the average examinee, or perhaps based on prior information about the examinee (such as might come from a previous test, or a counselor s assessment) All of these situations, and many more, are problematic with classical test theory as the measurement framework because examinee test scores are dependent on the particular sample of items and their level of dif culty What is needed, if the goal is to tailor or adapt the administration of tests to examinees, is an approach to ability estimation that is not test dependent The in uence of the particular items on the test administered to the examinee needs to be accounted for Frederic Lord and Harold Gulliksen from the Educational Testing Service in Princeton, NJ, and many other psychometricians in the 1940s and 1950s, were interested in producing a psychometric theory that assessed examinees in a way that did not depend directly on the particular items that were included in a test The idea was that an examinee may score high on an easy test or lower on a hard test, but there was a more fundamental ability that the examinee brings to any given testing situation that does not change as a function of the sample of items administered It is this more fundamental characteristic of the examinee that is usually of interest to the assessment specialist and it is this more fundamental characteristic, referred to as a latent variable , that is of interest in modern test theory, often called item response theory The construct of interest, or ability measured by the test, is more fundamental than test score because ability scores do not change with the particular choice of items in a test Of course they can change over time ue to learning, life changes, experiences, etc If this capability were not present, the new psychometric models would have very limited utility The purpose of item response theory (IRT) is to overcome the shortcomings of classical test theory by providing a reporting scale on which examinee ability (the construct measured by the test) is independent of the particular choice of test items that are administered, and item statistics de ned over the same reporting scale are independent of the particular examinee.

To be reliable, a sampling test must make sure that its system is stable before triggering any further interactions Sampling tests need to be structured as a series of phases, as shown in Figure 273 In each phase, the test sends a timulus to prompt a change in the observable state of the system, and then waits until that change becomes visible or times out.

Brown eld Development We don t always have the luxury of building a new system from the ground up Many of our projects have started with an existing system that must be extended, adapted, or replaced In such cases, we can t start by building a walking skeleton ; we have to work with what already exists, no matter how hostile its structure That said, the process of kick-starting TDD of an existing system is not fundamentally different from applying it to a new system although it may be orders of magnitude more dif cult because of the technical baggage the system already carries Michael Feathers has written a whole book on the topic, [Feathers04] It is risky to start reworking a system when there are no tests to detect regressions The safest way to start the TDD process is to automate the build and deploy process, and then add end-to-end tests that cover the areas of the code we need to change With that protection, we can start to address internal quality issues with more con dence, refactoring the code and introducing unit tests as we add functionality The easiest way to start building an end-to-end test infrastructure is with he simplest path through the system that we can nd Like a walking skeleton, this lets us build up some supporting infrastructure before we tackle the harder problems of testing more complicated functionality.
