Item sampling and/or multiple matrix sampling techniques have been recommended for a variety of purposes. For some of these purposes, it must be assumed that examinee performance on a set of items is unaffected by the conditions under which the items are taken (i.e., no context effect exists). In this paper factors that may lead to a context effect among high school students are discussed. The net effect of such factors on examinee scores for an English test and a mathematics test is investigated empirically. For the English test there was little support for the existence of a context effect, However, a definite context effect was found for the mathematics test.
