Specific art portfolio collections or any specific portfolio collection, as the title implies, includes evidence generated by one content area. In the instance of an art portfolio this might include evidence such as preliminary sketches, a final drawing, and a written self-critique. Rating Scales Assessing portfolio collections is somewhat more complex than scoring a standardized test because portfolio collections take into consideration individual and original responses as opposed to fixed answers. One of the most comprehensive ways of assessing portfolio content is through the use of rating scales. Rating scales list the criteria or objectives for an assignment.
Rubrics are also a good form of portfolio assessment.
Considerably more complex and detailed than rating scales, rubrics are very specific in stating the degree to which each criterion for the lesson has been met. Assessment of portfolio collections should be a compilation of scores derived from the individual assignments, not one arbitrary grade assigned for the entire scope of the collection. Of utmost importance is reflective self-assessment wherein students are given an opportunity to discuss processes and personal change in attitudes, opinions, and understanding. Benefits of Portfolio Collections Keep in mind that there is no best or singularly correct method for compiling portfolio collections nor for evaluating and assessing the contents. While certain objectives and standards may be set for a particular class, each student is an individual and for this reason work will vary from one student's portfolio collection to another.
