The Challenge of Classroom Assessment

Teachers’ classroom assessments are high stakes. They are the basis for decisions about promotion of students from one grade to the next, the awarding of graduation diplomas and scholarships, and they are often consequential for admission to post-secondary studies.

High stake decisions are not the only purposes to which classroom assessments are put. Teachers use classroom assessments to inform students about whether they have mastered the knowledge they are supposed to have acquired, to plan and modify the teachers’ instructional plans, to provide opportunities for students to practice and apply what they have learned, to determine the knowledge and understanding students need to progress to the next level, to communicate to the student and the student’s parents how the student is doing, to motivate students and more.

Teacher classroom assessment occurs daily and is labour intensive. Observation of student performance happens frequently albeit unsystematically throughout the day. Teachers create numerous kinds of assessments. Assessments include quizzes, tests, and opportunities for demonstration and oral presentations. Appraising performance on each of the teacher-created assessments is time-consuming.

The challenge with teacher assessment is that there isn’t agreement among teachers about what should be assessed. Teacher assessments are driven by a teacher’s professional judgment and, thus, by the teacher’s values. Some teachers believe that assessment should be confined to performance in the subject being assessed. Others believe that assessment should consider student attitude, motivation, or work ethic. Most teachers are aware that a student’s background, gender orientation, and/or personality are not relevant considerations for assessment.

Some teachers argue that assessment should be confined to the student’s performance in the classroom. Others say that homework is an extension of the classroom. Those opposed to assessing homework point out that homework is a form of practice – the most important facet of which is the teacher’s feedback. Others take a developmental perspective, arguing that a formal assessment of homework (beyond just the teacher’s feedback) is acceptable, but that teachers should take a developmental perspective by weighting the assessments more heavily the closer they are to the end of the unit. Some teachers are opposed to assessing homework because it is difficult to determine whether the student worked independently or with the assistance of others.

Teachers sometimes say that colleagues place too much value on print-based assessments (quizzes, tests, essays, reports, etc.) penalizing students who understand the material but have difficulty demonstrating what they know in writing. These teachers supplement written assessment with other demonstrations of understanding (oral presentations, dramatizations, diagrams, use of manipulatives, etc.).

Educational researcher Susan Brookhart and her colleagues reviewed the literature devoted to grading over the past 100 years with a particular emphasis on the meaning and value associated with grades. Among the many important findings of this review were:

·       Teachers primarily assess achievement using tests.

·       Teachers assess many non-academic factors in assigning grades, including effort, improvement, perceptions of student ability, completion of work, and other student behaviour.

·       The relative emphasis teachers assign to academic and non-academic factors differs markedly across teachers.

·       Assessment varies considerably by grade level.

The conclusion that Brookhart and her colleague draw is worth quoting at length:

This review suggests that most teachers’ grades do not yield a pure achievement measure, but rather a multidimensional measure dependent on both what the students learn and how they behave in the classroom. This conclusion, however, does not excuse low quality grading practices or suggest there is no room for improvement. One hundred years of grading research have generally confirmed large variation among teachers in the validity and reliability of grades, both in the meaning of grades and the accuracy of reporting.

Their conclusion is troubling. Inconsistency in the assessment process means that teachers other than the one who made the assessment find it difficult to know how to interpret their colleague’s assessment. It takes a leap of faith to believe that, in the aggregate, teacher assessments can support the high stakes decisions on which they are based.

Some ministries and school boards try to reduce the variability of teacher assessments by encouraging the use of performance standards and separating the appraisal of academic and non-academic factors. While those efforts are to be commended, those practices are also inconsistent across jurisdictions.

Notwithstanding these efforts, much more work is needed to improve classroom assessment, including clarifying the purpose of assessment, distinguishing between academic and non-academic factors, improving teacher preparation in assessment and in communicating results of assessment to students, parents, and others who make use of assessment results.
