Common Core State Standards (CCSS)
⚠️ CRITICAL CLARIFICATION
Common Core State Standards (CCSS) is NOT a test or exam.
CCSS is a set of academic standards - learning goals that outline what students should know and be able to do in English Language Arts (ELA) and Mathematics at each grade level from kindergarten through 12th grade.

What Are Common Core State Standards?
📚 Understanding CCSS
The Common Core State Standards are a set of high-quality academic expectations in English Language Arts/Literacy and Mathematics that define what students should understand and be able to do at the end of each grade level.
Key Characteristics:
- Adopted by States: 41 states, the District of Columbia, four territories, and the Department of Defense Education Activity have adopted CCSS
- Two Core Subjects: English Language Arts/Literacy and Mathematics only
- K-12: Standards span from Kindergarten through 12th grade
- College and Career Ready: Designed to prepare students for success in college and careers
- Evidence-Based: Built on research and evidence about what works in education
- Internationally Benchmarked: Aligned with expectations in high-performing countries
States That Adopted Common Core (as of 2025):
Alabama, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida (modified), Georgia, Hawaii, Idaho, Illinois, Indiana (modified), Iowa, Kansas, Kentucky, Louisiana (modified), Maine, Maryland, Massachusetts, Michigan, Mississippi, Missouri (modified), Montana, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oregon, Pennsylvania, Rhode Island, South Carolina (modified), South Dakota, Tennessee (modified), Utah, Vermont, Washington, West Virginia, Wisconsin, Wyoming, plus D.C.
States That DO NOT Use Common Core
The following states have not adopted Common Core or have fully replaced it with state-specific standards:
- Texas: Uses Texas Essential Knowledge and Skills (TEKS)
- Virginia: Uses Virginia Standards of Learning (SOL)
- Alaska: Uses Alaska Standards
- Nebraska: Uses locally developed standards (no state standards)
- Oklahoma: Replaced Common Core with Oklahoma Academic Standards
Note: Some states listed above use standards very similar to Common Core but under different names.

Understanding Common Core Performance Levels
How Students Are Evaluated
Most Common Core-aligned assessments use four performance levels:
| Performance Level | Description | Achievement Status |
|---|---|---|
| Level 4 - Exceeds Standards | Demonstrates thorough understanding and ability to apply knowledge | ✅ Exceeding Grade Level |
| Level 3 - Meets Standards | Demonstrates adequate understanding of grade-level content | ✅ At Grade Level (Proficient) |
| Level 2 - Partially Meets Standards | Demonstrates partial understanding; needs additional support | ⚠️ Below Grade Level |
| Level 1 - Does Not Meet Standards | Minimal understanding; significant gaps in knowledge | ❌ Well Below Grade Level |
Goal: All students should reach at least Level 3 (Meets Standards) to be considered proficient and on track for college and career readiness.

Preparing for Common Core Assessments
For Students
📚 Master the Standards
Understand what's expected at your grade level. Ask teachers to explain grade-level standards.
📖 Read Widely
Common Core emphasizes reading complex texts. Read challenging books, articles, and informational texts.
✍️ Write Regularly
Practice all writing types: arguments, explanatory essays, and narratives with evidence and analysis.
🔢 Understand Math Concepts
Don't just memorize procedures. Understand WHY math works and how to explain reasoning.
🔍 Show Your Work
Common Core values problem-solving process. Always show steps and explain thinking.
💻 Practice Digital Format
Most tests are computer-based. Practice with online tools and typing responses.
For Parents
- Understand the Standards: Review what your child should know at their grade level
- Support Homework: Help with homework but encourage independent problem-solving
- Read Together: Discuss books, ask comprehension questions, analyze texts
- Real-World Math: Practice math in everyday situations (cooking, shopping, budgeting)
- Communicate with Teachers: Stay informed about your child's progress toward standards
- Access Practice Materials: Many states provide free practice tests online
- Encourage Effort: Focus on growth and learning, not just test scores

Frequently Asked Questions
Is Common Core a test?
No. Common Core State Standards are learning goals - academic standards that describe what students should know and be able to do. Various tests (like Smarter Balanced) measure whether students are meeting these standards.
Do all states use Common Core?
No. As of 2025, 41 states plus D.C. and four territories use Common Core or very similar standards. Texas, Virginia, Alaska, Oklahoma, and Nebraska use different state-specific standards.
Why was Common Core created?
Common Core was developed to ensure all students, regardless of where they live, graduate high school prepared for college and careers. It provides consistent, clear standards so families moving between states find similar expectations.
When are Common Core tests administered?
Most Common Core-aligned assessments are given in spring (March-May) each year. Specific dates vary by state and district. Tests are typically given to students in grades 3-8 and selected high school grades.
Are Common Core tests timed?
Tests vary by state. Smarter Balanced assessments are untimed - students work at their own pace. Other state tests may have time limits. Check with your state's assessment.
How long does each test take?
Varies by grade and subject. Generally, each subject (ELA or Math) takes 3-4.5 hours, administered over multiple days or sessions. Students do NOT sit for the entire time at once.
Do Common Core test scores affect grades?
Usually no - standardized test scores typically do not affect report card grades. However, they may impact promotion decisions, graduation requirements, or placement in some states. Check local policies.
Can students opt out of Common Core tests?
Policies vary by state. Some states allow opt-outs while others require participation. Check your state's education department website for specific opt-out policies and procedures.
When are results released?
Test results are typically released 2-3 months after testing, usually in late summer or early fall. Schools communicate results to families through reports and parent conferences.
Important Reminders
- CCSS Are Standards, Not Tests: Common Core defines WHAT to learn; tests measure HOW WELL students learned it
- Testing Varies by State: Check your state education website for specific test names and dates
- Spring Testing: March-May 2026: Most Common Core assessments given in spring
- Grades 3-8 Tested: Most states test annually in elementary and middle school
- Computer-Based: Most assessments are digital; practice with online formats
- Multiple Sessions: Tests spread across several days - not taken all at once
- Focus on Learning: Standards emphasize deep understanding, not memorization
- Check Local Information: Contact your school/district for exact testing dates and procedures
Final Thoughts
Common Core State Standards represent a shift toward deeper learning, critical thinking, and real-world application of knowledge. Rather than memorizing isolated facts, students are expected to understand concepts deeply, explain their reasoning, and apply learning to new situations.
Assessments measuring Common Core standards evaluate not just what students know, but what they can do with that knowledge. Success requires consistent effort throughout the school year, not just test preparation. Students who engage actively in class, complete assignments thoughtfully, read widely, and practice problem-solving regularly will be well-prepared for Common Core assessments.
Remember that these tests are one measure of academic progress. They provide valuable information about student learning but don't capture everything a student knows or can do. The ultimate goal is college and career readiness - developing skills and knowledge that will serve students throughout their lives.
Best wishes to all students working toward Common Core standards mastery!
⚠️ Disclaimer: This guide provides general information about Common Core State Standards and associated assessments for 2025-2026. Common Core is a set of academic standards, not a testing program. Specific assessments, testing dates, and procedures vary significantly by state and district. Always verify information with your local school district and state education department website. Testing schedules are subject to change. Information is accurate as of October 2025.
