Precision is a key facet of test development, with score reliability determined primarily according to the types of error one wants to approximate and demonstrate. This article identifies and discusses several primary forms of reliability estimation: internal consistency (i.e., split-half, KR-20, a), test-retest, alternate forms, interscorer, and…

Many educators consider grades calculated from statistical algorithms more accurate, objective, and reliable than grades they calculate themselves. But in this research, the authors first asked teachers to use their professional judgment to choose a summary grade for hypothetical students. When the researchers compared the teachers' grade with the…

Studies based on longitudinal data focus on the change and development of the situation being investigated and allow for examining cases regarding education, individual development, cultural change, and socioeconomic improvement in time. However, as these studies require taking repeated measures in different time periods, they may include various…

The design, delivery and assessment of a complete educational scheme, such as a degree programme or a professional qualification course, is a complex matter. Maintaining alignment between the stated aims of the curriculum and the scoring of student achievement is an overarching concern. The potential for drift across individual aspects of an…

In the assessment of aural skills of second language learners, the study of the inclusion of visual stimuli has almost exclusively been conducted in the context of listening assessment. While the inclusion of contextual information in test input has been advocated for by numerous researchers (Ockey, 2010), little has been said regarding the…

A follow-up study of two instruments for evaluating college writing was conducted. The experimental scale (E Scale) was developed in 1976 and revised for this study. The control scale (C Scale) was described in the literature in 1977. Ten English majors graded ten essays from diagnostic entrance exams. Both the E Scale and the C Scale were used,…

The effectiveness of the "read-comp" technique in assessing writing ability and the usefulness of a rubric and procedure devised for scoring read-comp samples and essays were evaluated. Subjects were 100 freshman students enrolled in general and remedial English classes in a 6-week summer session at Indiana University of Pennsylvania.…
