This digest explains why teacher comments on report cards are important, offers suggestions on how to construct effective comments, points out words or phrases to be cautious about using, and indicate sources of information for report card comments. Teacher comments are important in that they often convey information that is not completely explained by the grade. Well-written comments can give parents and children guidance on how to make improvements in specific areas. When written in a positive and informative manner, comments can address a variety of issues while maintaining the dignity of the child. Some phrases are suggested to indicate ways in which the child needs help. Teachers should be careful not to portray a child's ability as fixed and permanent, and they should be aware that the student will probably read the comments. Teachers should have many sources from which they can derive information on each child to support the comments made on the report card. The most commonly used sources of information are examples of student work and test results. Another rich source of information is the student observation. Observations should be documented for each child in a variety of situations. (Contains 10 references.) (SLD).
