Until recently there has been no nationally acceptable test for assessing reading for the higher grades (Five and Six) of the elementary schools in Greece. As part of an effort to validate such a test, evidence was gathered from teachers' rating scales. Seventy-two teachers from Fifth and Sixth Grades all over Greece evaluated their 1377 students' reading ability prior to the administration of a standardised reading test. The teachers were instructed to rate each student's reading achievement, disregarding effort, intelligence, behaviour and attendance. Within class correlation coefficients were computed to determine whether teachers' personal judgement (ratings) and students' actual performance on the reading test were correlated. The standardised reading test and the teachers' ratings were found to have a strong correlation. The match between Greek teachers' assessments of student reading levels and the scores obtained using a newly standardised reading test is reported, in order to examine the extent to which teacher ratings and standardised test results of students yield the same information. The rationale of this study is to investigate whether a new standardised Greek reading test can provide an alternative tool for the assessment of Greek primary education.Reading in Greece is taught as part of a linguistic lesson called 'My Language'. Assessment is an ongoing educational process, on the basis of which the pupil's learning progress is monitored (Kassotakis, 1994;Mavromatis, 1996). Its main aim in primary schools is to improve the students' learning by improving the teaching instruction and the operation of the schools. Assessment in Greek primary schools is not of a competitive or selective nature (Ypepth, 1994).In a linguistic lesson, classroom teachers can assess their students in the following ways:on daily oral reading on the passage that is presented in the chapter; by students' performance in the different written exercises in their textbooks; by short composition essays that students have to write two to three times per week; by revision assignments done in school, either oral or written; by formal tests written by teachers three times a year (Ypepth, 1994).
