An Investigation on the Accuracy of Teachers’ Judgments on Students’ School Achievement
Abstract
Teacher-based assessment of students’ school achievement is a process in which collection of
information on students’ performance is needed to allow teachers to understand what and how
students achieve. This process involves the development of teachers’ judgments. This study
investigated the predictive utility of an informal teacher-made achievement test on teachers’
judgments to students’ academic performance. The study involved 166 primary school students
(mean age 11.7) and their respective 46 teachers. Main findings indicated that: 1. teachers’
general judgments did not distinguish the difference between students with low achievement
and underachievement, and 2. teachers’ judgments with the use of an academic performance
rating scale could differentiate low achieving from underachieving students. It is suggested that
the accuracy of teachers’ judgments on students’ school achievement is increased when
domain-specific and multi-point scales of students’ academic performance and behavior are
used
