14.2


(14.2) Consider norm referenced assessment and criterion referenced assessment. Are there advantages to both? Are there disadvantages?
By ranking test takers based on comparing their performances to that of their peers, norm referenced assessments such as IQ and developmental screening tests can help educators and families detect possible special needs in students. Other norm referenced assessments such as SAT, ACT, GRE help colleges make admission/scholarship decisions. Another advantage of norm referenced assessment is its practicality, or that it’s relatively easy for teachers/programs to give (one test for everyone). A disadvantage of norm referenced assessment, when applied as a grading system inside a classroom, is that it could potentially discourage students from helping one another (group study/peer tutoring, etc.) since others’ doing poorly is an advantage for one student under the norm referenced grading system. It might also discourage high achieving students from trying their best when their minimal efforts generate high rankings/grades. Similarly, it might be frustrating for low achieving students and discourage them from achieving their full potentials when their best efforts generate low rankings/grades.
Criterion referenced assessments report the students’ performances strictly based on whether they correctly answered a set of questions or not. They are helpful when educators need to find out whether or not the students have learned a particular knowledge or skill in a curriculum. The teacher can then go back to teaching the knowledge or skill when the students didn’t ace the test or move on to teaching a new knowledge or skill when the students aced the test. Another advantage of criterion referenced assessment is that it can be tailored to meet the student’s special needs (assessments based on IEP goals), thus helping the student in achieving his/her fullest potential. A disadvantage of criterion referenced assessments is that they usually cannot be generalized beyond any specific program or class. Another disadvantage is that criterion referenced assessments that all students can succeed in could potentially be difficult and time-consuming to develop (low practicality).

  1. Xiao,

    Many state standardized tests are both criterion referenced and norm referenced. Hopefully, we will soon be able to used standardized tests not only to track student progress in a broad sense as compared to other school districts, but to pinpoint specific things that students need to work on: like comma placement, or graphing linear equations. If you had to make a CRA measuring something small, like a student's ability to graph a linear equation, it might not be very time consuming. Hopefully, this new trend in standardized testing will take away some of the most time consuming parts of creating CRAs.

  2. Xiao,

    This was very interesting to read. I never really looked at the norm referenced assessments in that manner. It potenitally could discourage students from offering help or working collaboratively with their peers. It becomes almost like a competition to see who performs the best. It reminds me of students in my graduating class who determined who were the smartest students in the school based solely on their ACT scores. One test does not simply define academic achievement.
