Final answer:
Assessments 1) and 2) are criterion-referenced, while assessment 3) is norm-referenced.
Step-by-step explanation:
1) The assessment described is criterion-referenced (CR) because it is evaluating basic mathematics skills for the purpose of determining a student's need for academic support. It is focused on specific criteria or standards that indicate the level of mastery.
2) The assessment described is also criterion-referenced (CR) because it is provided by the district twice each year to determine student mastery of state performance standards. It is focused on specific criteria or standards that indicate whether students have met the required level of proficiency.
3) The assessment described is norm-referenced (NR) because it involves a pretest and posttest that evaluate teaching effectiveness and students' learning progress in mathematics. It is comparing the students' performance to a larger population and providing referential scores.
