Introduction: Why This Matters for Every College-Bound Family

Choosing a college major has never been more competitive. Some programs are so impacted that even top students are turned away. At the same time, many parents don’t realize that colleges openly publish data—test scores, GPA ranges, admissions criteria—that can help families better plan and position their students.

At Advanced College Planning, we believe in giving families the tools and data they need to make smarter choices. In this post, you’ll learn what impacted majors really are, how to access and decode UC impaction lists, and how to leverage the Common Data Set (CDS) to strategically benchmark your child’s profile.

What Is an Impacted Major?

An impacted major is a college major that receives more qualified applicants than it has space to admit. These programs often require higher GPAs, additional prerequisites, or supplemental applications—even within public institutions like the University of California (UC) and California State University (CSU) systems.

Common Examples of Impacted Majors:

• Computer Science
• Nursing
• Business Administration
• Psychology
• Engineering
• Biological Sciences

Because of this, students applying to these programs face significantly higher admissions standards—even at colleges where they would otherwise be strong candidates.

Advanced Tip: Some impacted majors have internal admission hurdles even after a student is accepted to the university. Always check department-specific criteria.

How to Find the UC Impaction List

The University of California system updates its impaction list annually, showing which programs are capped at each campus. These lists are publicly available and crucial for planning.

Where to Find It:

• UC Impaction Page (varies by year)
• High school counselors may have PDF summaries
• Some nonprofit sites like Alabama Possible share updated lists

What to Look For:

• Major name (it may vary slightly across campuses)
• Supplemental application or portfolio requirements
• Higher GPA/test score thresholds
• Transfer vs. freshman impaction rules

Knowing which campuses and majors are impacted allows families to:

• Apply earlier
• Identify less competitive alternatives
• Strengthen major-specific extracurriculars

Pro Tip from Advanced College Planning: Encourage your student to research parallel majors (e.g., data science instead of computer science) that may be less impacted but offer similar career paths.

Understanding the Common Data Set (CDS)

The Common Data Set is an annual report published by colleges and universities that includes detailed information on admissions, demographics, academics, and more. It’s a goldmine for families who want to dig deeper than basic college brochures.

Focus on Sections C7–C9:

These sections reveal how schools evaluate applications and the academic profile of accepted students.

CDS Section C7: Factors Considered in Admission

Includes a checklist of what each school considers:

• Academic GPA
• Standardized tests (if still used)
• Class rank
• Essays
• Recommendations
• Extracurriculars
• Interviews

This gives insight into what the college values most.

CDS Section C8: GPA and Class Rank Distribution

Shows the percentage of admitted students who fall into certain GPA ranges (e.g., 4.0+, 3.75–3.99). Some CDS reports also list average unweighted and weighted GPA.

CDS Section C9: SAT/ACT Scores

Even if schools are test-optional, this section shows what scores competitive applicants submitted. You’ll find:

• Middle 50% score ranges
• Percent of enrolled students submitting scores

Using the CDS to Benchmark Your Student

Once you access a college’s CDS, compare your student’s profile with the stats from admitted students.

Example:

If UCLA’s CDS shows that 80% of admitted students had a GPA above 4.0 and an SAT between 1420–1550, and your student has a 3.8 GPA with a 1340 SAT, UCLA may be a reach school—especially for an impacted major like engineering.

How to Use CDS Data:

• Target Schools where your student is at or above the average
• Reach Schools where your student is below the 50% mark
• Safety Schools where your student exceeds all listed ranges

At Advanced College Planning, we use the CDS in every family consultation to customize college lists that are data-driven and realistic.

Interview Spotlight: UC Admissions Officer Shares Advice

We spoke with a current University of California admissions officer who asked to remain anonymous but offered valuable insight.

Q: What’s your advice to families worried about impacted majors?
A: “Start planning early. We look at coursework, not just senior year. Students applying to impacted majors should show academic rigor in that subject area—like AP science or calculus—and back it up with related extracurriculars.”

Q: Do you recommend using the CDS?
A: “Absolutely. It’s the most transparent way to understand how your student compares. Parents should be using it, not just relying on college rankings.”

Top 7 FAQs About Impacted Majors and CDS

 

1. How do I know if a major is impacted at a specific UC or CSU?

Check the latest UC/CSU impaction list, available on their admissions websites or from your high school counselor. Each school may have different impaction rules even for the same major.

 

2. Can I switch out of an impacted major after I’m admitted?

Not always. Many impacted programs limit internal transfers or require high GPA thresholds. It’s best to apply directly to your intended major if possible.

 

3. What if my student’s GPA doesn’t match CDS data?

That depends. If the school is holistic in admissions (see CDS Section C7), strong essays, leadership, and community impact can help—but it’s important to apply broadly.

 

4. Are test-optional schools still reporting SAT/ACT data?

Yes. Even test-optional schools report score ranges in CDS Section C9. This helps you understand the academic profile of those who did submit scores.

 

5. Where do I find a college’s Common Data Set?

Search “[College Name] + Common Data Set + year.” Many are available on school websites, but you can also find them through third-party platforms like collegedata.com or CCMR with Ms. Thrash.

 

6. Should we avoid impacted majors entirely?

Not necessarily. But your student should strengthen their academic resume in that field and consider applying to less competitive campuses or similar majors.

 

7. What’s the best strategy for applying to an impacted major?

• Apply early (before priority deadlines)
• Take rigorous coursework in the subject area
• Build a major-aligned extracurricular resume
• Include a strong personal statement that speaks to your interest in the major
