Writing an AP Calc Assessment

• Include calculator and non-calculator items

• Include multiple choice and free response items

• Write questions that reflect learning targets and success criteria

• Determine scoring rubric for FRQs before administering the assessment (see below)

​

Questions to Include

• Interpretation of a derivative in context using correct units

• Particle motion questions about when a particle is at rest, slowing down, or speeding up

• Interpretation of a velocity graph

• Rate In/Rate Out problem

• FRQ where the given function represents a quantity

• FRQ where the given function represents a rate

​

Grading Tips

We recommend that you prepare a rubric for the free response items before you begin grading your quizzes or tests. Know what information is necessary for a complete and correct response and award points when a student presents that information. Many of the “Why did I get marked down?” questions are eliminated when you share the components that earn points

​

Reflections

• We strongly suggest modifying released free response questions from previous exams to provide the stem for the quiz question. Students must learn how to interpret functions involving strange contexts and be able to carefully read an extended question stem.

• Quizzes are a great way to continually emphasize multiple representations. Functions represented in tables and graphs are a great alternative to functions represented in analytical form (as an equation). 

• Units are critical! Students must use proper units in their final answer, especially when interpreting a derivative. Similarly, look for precise language. Vague references to “the graph”, “the function”, or “the derivative” will not earn points on the AP exam.
