Essential to understanding Marzano's proposed grading system in a brief introduction to the idea of the conjunctive method of assigning final grades. Using weighted or unweighted averages of specific 'measurement topics' (academic and non-academic) addressed in the course, a final score could be created (Marzano, 2006). Typically, these measurement topics are graded on a 0.0 to 4.0 scale, using half-point increments. The school can then construct its own scheme along this scale to translate these average measurement topic grades into an overall letter grade of A, B, C, or D if desired (Marzano, 2006). Marzano, however, warns against the solitary use of overall grades as they are rather arbitrary in terms of cutoff points (2006). The conjunctive method sets of a scoring system of weighted topic scores leading to a computer overall grade. Here, according to Kifer (1994), performance on one measurement topic can "compensate" for performance on another and bring the overall grade up. This method is advantageous, then, because sometimes the average score does not represent the typical score in a set because the scores in the set are very different.
In his idea for reformatted report cards, Marzano suggests including overall letter grades (by subject area & computed using a conjunctive approach) at the top of the report card (2006). Below would be a detailed breakdown of student performance in each individual measurement topic, which contributed to their overall letter grades. Next, Marzano proposes the notion of a report card with no overall grade and a focus strictly on measurement topic performance (2006). In mathematics, for example, measurement topics could include number systems, estimation, addition/subtraction, and multiplication/division (Marzano, 2006). The average score for these topics would then be included at the top of the report card, with no attached letter grade equivalent (Marzano, 2006). Non-academic measurements could be made in "life skills" areas like participation, work completion, behavior, and working in groups (Marzano, 2006). Each subject area could be broken down in a similar manner. Additional transcripts could be attached to track student progress and overall GPA (Marzano, 2006).
Additionally, an article from Education World (1998) notes the overall failure of the system of assigning overall letter grades with no other criteria taken into consideration. New methods of creating grades for report cards, then, are being discussed amongst education professionals of today. Similarly to Marzano's (2006) proposal, these new report cards, which focus heavily on lists of specific skills in a variety of subject areas and progress through these areas with the help of teacher narration, are believed to be more objective than the letter grading system (educationworld.com, 1998). Parents, however, feel that these report cards are vague, complex, and frustrating due to the overwhelming amount of educational jargon included in their content (educationworld.com, 1998).
Hu (2009) reports that one grading system growing widely popular by schools administrations and educators countrywide has been accepted by the school district of Pelham, New York. The type of report cards issued in this school, too, bear great resemblance to the system recommended by Marzano (2006). Doing away with overall letter grades altogether, the system at Pelham issues standards-based report cards with numbers indicating how students are faring on a number of specific skills like "decoding strategies" and "number sense and operations". The lowest number achievable, 1, cites that the student is not working up to New York State Standards while a score of 4 indicates the ability to "meet standards with distinction". Officials in the district favor the new kind of grading system the report cards present, yet parents have shown great opposition to giving up their old interpretation of their children's grades.
In fact, standards-based report cards are sweeping the nation in a trend-like fashion. Matturro notes that many school districts send home detailed accounts of each subject's content, student progress, social behavior, work habits, and learning skills (2009). In one Kentucky school district alone, 11 standards to be met by students are listed under social reading (Matturro, 2009). On the other hand, Connecticut has just three standards to be met listed under the subject of reading (Matturro, 2009). Currently, in Rockville, Maryland, schools abide by four different grading scales consisting of a mix of letters and numbers.
Although new and under trial supervision, a movement for report card reform is taking the nation by storm, beginning with the popularity of standards-based report cards. Educators and school officials embrace the new systems as a checklist of skills crucial to learning in both academic and non-academic subject matter. Parents, despite the positivity from school personnel, parents appear reluctant to latch on to the new trend.
