It is shown that empirical mental test P - P plots are approximately equal to theoretical item-item curves, at least for long tests administered to many people. This result is important because it leads to (1) a distribution free method for estimating points on item-item curves; (2) a general method for defining estimates of item parameters; and…

The construction and norming of Form N of the Air Force Officer Qualifying Test (AFOQT) is described. The new form serves the same purpose as its predecessor and possesses basically the same characteristics. References are made to the research which provided the basis for most of the changes. Other changes were made because of the admission of…

Comparisons of corresponding values of phi and kappa coefficients were made for 270 instances of data generated by a Monte Carlo technique to simulate a test-retest situation. Data were generated for distributions with the same mean but three different levels of standard deviation, standard error of measurement and cutting score. Ten samples of…

The effects of varying the formats of behavior rating scale items on teacher ratings of student hyperactivity were investigated. Two hundred forty-two teachers were asked to rate a variety of children; some had been identified as hyperactive by physicians, parents, or teachers; some were not considered hyperactive; and others were randomly…

One aim of criterion-referenced testing is to classify an examinee without reference to a norm group; therefore, any statements about the dependability of such classification ought to be group-independent also. A population-independent index is proposed in terms of the probability of incorrect classification near the cutoff true score. The…

The School Readiness Rating Scale was developed to help teachers organize their suggestions to parents about how parents can help their children prepare for beginning reading experiences. The scale surveys five important aspects of readiness for beginning reading: visual perception, visual motor perception, auditory perception and discrimination,…

Tailored testing increases the efficiency of tests by individually selecting for each person a set of items from an item pool so that the difficulty of the items selected will be such as to maximize the information provided by the score. The tailored testing procedure designed by Cliff orders persons and items on a common ordinal scale and…

The Verbal Measure of Information Rate (VMIR) is a measure of information rate which reflects the elements, features, and changes in a complex environment. Subjects rated 14 bipolar adjective pairs to indicate an appropriate description of the learning situation or information load (simple-complex, novel-familiar). The measure was administered to…

A method is described which used the Rasch model for combining information across administrations of the same items in different tests to different student populations. The method was used in conjunction with the composite point biserial and mean square fit to provide more valid information about item quality. Over 700 items were administered to…

The initial steps necessary for constructing an analogies test are described. Basic mathematics being the context, the aim of the test is to predict student performance in research statistics courses characteristic of graduate education and social science programs. Items involving analogies in a quantitative context were built, sorted into two…

THE JOHNS HOPKINS PERCEPTUAL TEST (JHPT), REVIEWED IN THIS PAPER, WAS DESIGNED TO MEET THE NEED FOR A BRIEF, EASILY ADMINISTERED, NON-VERBAL INSTRUMENT TO ASSESS THE INTELLECTUAL FUNCTIONING OF CHILDREN. THE DATA ON THIS INSTRUMENT INDICATES THAT IT IS RELATIVELY CULTURE FAIR AND USEFUL FOR TESTING CHILDREN WHOSE PHYSICAL HANDICAPS PRECLUDE THE…

THE VALIDITY OF AN EDUCATIONAL ACHIEVEMENT TEST DEPENDS UPON THE CORRESPONDENCE BETWEEN SPECIFIED EDUCATIONAL OBJECTIVES AND THE EXTENT TO WHICH THESE OBJECTIVES ARE MEASURED BY THE EVALUATION INSTRUMENT. THIS STUDY IS DESIGNED TO EVALUATE THE EFFECT OF STATISTICAL ITEM SELECTION ON THE STRUCTURE OF THE FINAL EVALUATION INSTRUMENT AS COMPARED WITH…

THE REVISION OF THE HISKEY-NEBRASKA TEST OF LEARNING APTITUDE (H-NTLA) WAS UNDERTAKEN TO MODERNIZE THE TEST MATERIALS, TO EXTEND THE TEST, AND TO PROVIDE UP-TO-DATE NORMS ON DEAF SUBJECTS AND HEARING SUBJECTS. THE ITEMS CONSIDERED FOR THE REVISION WERE ADMINISTERED TO NORMAL HEARING, DEAF, AND RETARDED SUBJECTS AGED 3 TO 17 YEARS. FOLLOWING THE…

THIS STUDY WAS PHASE 1 OF A 2-PHASE PROJECT DESIGNED TO CHANGE TEACHER BEHAVIOR WITH THE OBJECTIVE OF IMPROVED CLASSROOM UTILIZATION OF NEW INSTRUCTIONAL MEDIA. PHASE 1 TRIED TO INCREASE TEACHER KNOWLEDGE OF MEDIA VIA A MONTHLY NEWSLETTER, "THE CIRCULATOR," DISTRIBUTED IN 5 DISSEMINATION PATTERNS TO 2,200 EDUCATORS IN PENNSYLVANIA. A…

LANGUAGE ENCODING AND DECODING PROCESSES WERE EXAMINED BY DETERMINING THE ABILITY OF SUBJECTS TO PREDICT OMISSIONS FROM A NATURAL LANGUAGE TEXT WHICH THEY HAD PREVIOUSLY PRODUCED THEMSELVES, AND BY COMPARING THIS PERFORMANCE WITH THAT OF OTHER SUBJECTS TO PREDICT OMISSIONS FROM THESE SAME TEXTS WHICH THE SECOND GROUP READ AT THE TIME OF…
