Missouri EOC Calculator Policy Finder

What is the “best calculator to use on the EOC MO”?

The “best calculator to use on the EOC MO” is not a single model, but rather the calculator that is permitted for your specific End-of-Course exam and one you are comfortable using. The Missouri Department of Elementary and Secondary Education (DESE) sets the policies, which vary by subject. For many key exams, an online version of the Desmos calculator is provided directly in the testing software. This means that for some tests, you won’t need to bring your own calculator at all. For others, a handheld calculator is allowed or required. Understanding the specific rules for your test is the most critical step in your preparation.

Missouri EOC Calculator Policy Formula and Explanation

The “formula” for determining the right calculator is based on the subject you are being tested on. Different courses have different requirements, ranging from no calculator to a full graphing calculator. For many math and science courses, a graphing calculator is the standard. However, it’s crucial to know that the online testing platform often includes an embedded Desmos calculator, which serves this purpose.

EOC Calculator Policy by Subject

Variable (Subject)	Meaning (Permitted Calculator Type)	Unit (Typical Tool)	Typical Range (Features)
Algebra I, Algebra II, Geometry	A graphing calculator is required for these assessments.	Handheld (e.g., TI-84) or Embedded (Desmos)	Graphing functions, statistical calculations, matrices. CAS is prohibited.
Biology, Physical Science	A graphing calculator is permitted for these science exams.	Handheld or Embedded (Desmos)	Scientific notation, logarithms, data analysis.
English I & II, American History, Government	No calculator is permitted or required for these exams.	N/A	N/A
Personal Finance	A basic or scientific calculator is typically sufficient.	Handheld or Embedded	Basic arithmetic, percentages, interest calculations.

Practical Examples

Example 1: Student Taking Algebra I EOC

• Inputs: The student is enrolled in Algebra I.
• Units: The subject determines the calculator type.
• Results: The student is required to use a graphing calculator. They can use the embedded Desmos graphing calculator provided during the online test or bring an approved handheld model like a TI-84. The handheld device must have its memory cleared and cannot have a Computer Algebra System (CAS).

Example 2: Student Taking Government EOC

• Inputs: The student is taking the Government EOC exam.
• Units: N/A.
• Results: The calculator policy for this subject is “None.” The student is not permitted to use a calculator. The questions on the exam will not require one.

Key Factors That Affect Your Calculator Choice

• Subject Matter: This is the most important factor. As shown in our tool, the requirements for Algebra I are different from English II.
• Online vs. Handheld: Missouri EOCs are primarily online. You must know if an online calculator (Desmos) is provided and decide if you prefer it over a handheld one.
• Prohibited Features: Calculators with Computer Algebra Systems (CAS), QWERTY keyboards, or wireless communication are strictly forbidden.
• Familiarity: The best calculator to use on the EOC MO is one you know how to operate efficiently. If you plan to use a handheld device, practice with it throughout the year.
• Test Mode: The embedded Desmos calculator is a specific “testing” version with some features disabled to ensure fairness. It’s wise to practice with the Desmos practice test version.
• District Policies: While DESE sets state policy, your local school district may have additional procedures, such as requiring memory to be cleared on handheld calculators before the exam.

Frequently Asked Questions (FAQ)

1. Can I use my phone as a calculator on the MO EOC?

No. Cell phones and any device with wireless communication capabilities are strictly prohibited during the exams.

2. What is a CAS (Computer Algebra System)?

A CAS is a feature on some advanced calculators that can solve algebraic equations symbolically (e.g., solving for ‘x’). These are not allowed on EOC exams to ensure students perform the algebraic steps themselves.

3. What is the best calculator for the Algebra 1 EOC in Missouri?

For the Algebra 1 EOC, a graphing calculator is required. You can use the provided Desmos online calculator or bring a handheld model like the TI-84 Plus.

4. Is the online Desmos calculator good enough?

Yes. The embedded Desmos calculator is a powerful graphing tool designed specifically for the test. It is fully sufficient to solve all problems on the exam.

5. Do I need a calculator for the Biology EOC?

Yes, a graphing calculator is permitted for the Biology EOC. It can be helpful for data analysis questions.

6. Where can I find the official DESE calculator policy?

The official policy documents are available on the Missouri Department of Elementary and Secondary Education (DESE) website, specifically under the Assessment (MAP) sections.

7. What happens if I bring a prohibited calculator?

You will not be allowed to use it. Test proctors are trained to check calculators, and using a non-approved device can lead to test invalidation.

8. Are there practice tools for the online calculator?

Yes, Desmos provides a practice version of their testing calculator on their website, allowing students to become familiar with the tool before the exam.
