Elementary school children's word guessing is studied, and the results from individual and collective testing conditions are compared. The participants are 764 students from the second, third, and fourth grades (ages 8-11, 541 students from mainstream regular classes and 223 students with learning disabilities). About half of these students are collectively tested in the classroom, and half of the students are individually tested in a separate room. The psychometric properties of the test are good for both individual and collective testing conditions. Students generally score higher in the collective condition compared to the individual condition in both groups. In the control group, this tendency is apparent in all three grades, whereas in the group of students with learning disabilities, it is demonstrated only in the third grade.S tudents learn and have to apply their learned knowledge in school; also, their knowledge and skills are frequently collectively assessed in the classroom for all the students of the same class. In Estonia, such forms of testing are practiced starting from the first grade (e.g., children take dictations and paraphrase and summarize presented texts in Estonian-language lessons). As a rule, psychological assessment (e.g., for developing individual learning plans) is individually carried out in a separate room on school premises, at a counseling service or a clinic. Although there are special screening tests that are carried out in groups, some of the tests for individual assessment are occasionally collectively used in the classroom (for Estonia, see Kikas, 2006). It is widely acknowledged that test results may depend on the child's emotional state, cultural background, and motivation; however, the role of assessment condition has received somewhat less attention. Thus, the goal of the present study was to study the effect of testing condition-individual versus collective-on wordguessing performance and to compare the effects for children with specific learning disabilities and normal control group.Several studies have shown the facilitative effect of school context and the collective testing condition on the performance of academic (verbal and mathematical) tasks.
