Assessment systems ensure that all students receive fair treatment in order not to limit students' present and future opportunities. They allow for multiple methods to assess student progress and for multiple but equivalent ways for students to express knowledge and understanding. Assessments are unbiased and reflect a student's actual knowledge. They are created or appropriately adapted and accommodations are made to meet the specific needs of particular populations, such as English language learners and students with disabilities. Educators provide students with instruction in the assessment methods that are used.
Bias review committees study and approve each large-scale assessment.
Assessment systems depend on educators who understand the full range of assessment purposes, use appropriately a variety of suitable methods, work collaboratively, and engage in ongoing professional development to improve their capability as assessors. Schools of education prepare teachers and other educators well for assessing a diverse student population. Educators determine and participate in professional development and work together to improve their craft. Their competence is strengthened by groups of teachers scoring student work at the district or state levels. Schools, districts, and states provide needed resources for professional development.
