Common App vs Coalition App vs UC vs Apply Texas: A Complete Comparison of the 4 Major U.S. Application Platforms

Published on May 14, 2026

Every year on August 1, when Common App opens, I always get calls from parents: “Teacher, I can’t find UCLA on Common App. Has it not opened yet?”

My answer is always the same: “The UC system does not use Common App. Berkeley, UCLA, and UCSD all require the UC Application, and the nine campuses share one application.”

Parents panic even more: “What about UT-Austin? MIT? Georgetown?”

The answer: UT-Austin uses Apply Texas, MIT uses its own MIT Application, and Georgetown uses its own GU Application. At least four application systems coexist among top U.S. universities, yet 90% of Taiwanese families only know Common App.

Using my 15 years of counseling experience, this article breaks down school coverage, essay differences, timeline checkpoints, and operational traps across these four major platforms.

1. School Coverage Across the 4 Major Application Platforms

Let’s start with the full picture:

Independent systems (outside the four above): MIT, Georgetown, U.S. Naval / Air Force Academy, and some public flagship universities such as Rutgers.

The reality: A Taiwanese senior applying to 12 schools may need to manage 3-4 platforms at the same time. The highest number I have seen was a student running five systems simultaneously: Common App + UC + Apply Texas + MIT + Georgetown.

2. Common App: The Main Battlefield for 90% of Students

2.1 Platform Features

Common App stands for Common Application. The system opens every year on August 1, and individual school deadlines arrive from October through January.

Biggest advantage: One PS can be submitted to every Common App school. Once the 650-word Personal Statement is ready, the same essay can go to 10, 20, or even 50 Common App schools.

Biggest trap: Supplemental Essays are where the real time cost lives. Yale has 5, Princeton has 4, Stanford has 7, and MIT has 5, though MIT is on its own system and uses prompts highly similar in structure to Common App-style supplements. A student applying to 12 schools may need to write 40-60 supplemental essays.

2.2 Operating Rhythm

This is the standard timeline I give Dr. G. students:

For detailed writing techniques, see “How to Write the 650-Word Common App Personal Statement.”

3. UC Application: An Independent Universe Outside Common App

3.1 Platform Features

The nine UC (University of California) campuses use one application: UC Berkeley, UCLA, UCSD, UC Irvine, UCSB, UC Davis, UC Santa Cruz, UC Riverside, and UC Merced. Register once, select the campuses you want to apply to, and use one shared set of essays.

The reality: UC is a system where “everyone can afford to apply, and almost no one can count on getting in.”

• No ED/EA → no early-application advantage; the only variables are essays + GPA + course rigor
• No SAT/ACT review → from 2025 onward, Test-Blind; even submitted scores will not be considered
• No recommendation letters → they do not even want rec letters

The entire review process is based on: GPA (with capped repeated courses and weighted AP/IB courses), PIQ essays, and extracurricular activities presented through the PIQs.

3.2 The Biggest Differences Between UC Application and Common App

Conclusion: Students applying to UC must write an additional 1,400 words over the summer: 4 PIQ essays × 350 words. For detailed PIQ strategy, see “How to Choose the 4 UC PIQ 350-Word Essays.”

4. Apply Texas: The Entry Ticket to Texas Public Universities

4.1 Platform Features

Apply Texas serves the UT system and TAMU system. The three most important schools are UT-Austin, UT-Dallas, and TAMU College Station.

Impact on Taiwanese students: The Top 10% Rule does not apply to international students. For international applicants, UT-Austin is therefore much harder than it is for Texas residents, with an admit rate of only around 8-10% for international students.

McCombs (business) and Cockrell (engineering): On Apply Texas, applicants must select a major separately, and each school has its own supplemental materials. Cockrell does not accept CS major undeclared; students must apply directly to a specific field such as CS or CE from the beginning.

4.2 The Most Common Mistakes Among UT-Austin Applicants

I have worked with 30+ students applying to UT-Austin. These are the three most common mistakes:

1. Thinking the deadline is 1/1: For UT-Austin, Apply Texas is due on 12/1, one month earlier than Common App RD
2. Not applying to honors programs: Plan II Honors, Turing Scholars (CS), and Canfield Business Honors all require separate applications; students are not “automatically considered”
3. Ignoring ApplyTexas and MyStatus: After submitting, students must use MyStatus, UT’s own portal, to upload the transcript and SAT score; many students think they are done after submitting Apply Texas

5. Coalition App (Scoir): An Awkward Presence After the Acquisition

Coalition Application was integrated into Scoir in 2023, and its user volume is now less than 20% of Common App’s. However, UNC (North Carolina Chapel Hill), UVA, UW Seattle, Maryland, and some other public flagships still support it.

Counselor’s honest take: If a school supports both Common App and Coalition, always use Common App. There are three reasons:

1. Common App has a more stable interface and fewer bugs
2. Your PS has already been written for Common App, so rewriting another essay for Coalition wastes time
3. Schools do not distinguish by platform during review, but Common App has more volume and admissions officers are more familiar with it

Exception: Some international scholarship pathways at UVA and UNC, such as UVA’s Jefferson Scholarship, accept only Coalition App. In that case, you must use it.

6. Independent Systems: MIT, Georgetown, UC Hastings, and Others

6.1 MIT

MIT does not use Common App. MIT uses its own MIT Application, which opens in August.

MIT’s review logic is completely different from other Ivy-level schools. For details, see “How to Write the 5 MIT Short Answers.”

6.2 Georgetown

Georgetown does not use Common App. Georgetown uses its own Georgetown Application, which opens only in October.

Georgetown’s “non-binding EA” is an unusual design. Students can apply Georgetown EA and also apply ED to another school at the same time without conflict.

6.3 Military Academies (United States Service Academies)

U.S. Naval Academy, Air Force Academy, West Point, Coast Guard, and Merchant Marine: all five service academies do not use Common App. Each has its own application system, and Taiwanese students usually cannot apply because they require U.S. citizenship and a congressional nomination.

7. Can the Same Essay Be Reused Across Platforms?

The most common parent question: “Teacher, after the 650-word PS is done, can we use it directly for the UC PIQs?”

Answer: no. Here is why:

The only thing you can borrow is material. For example, “my robotics club story” can appear from different angles in:

• Common App PS (deep narrative)
• UC PIQ #1 (about leadership)
• Apply Texas Topic A (about a community)
• Activities Section (150-word description)

But the presentation must be completely rewritten. If the same paragraph is copied and pasted directly, admissions officers at different schools will immediately sense the mismatch because their expectations for “narrative rhythm” differ.

8. Platform Selection Strategy: How Do You Decide Which Platforms a Student Should Use?

Case 1: Aiming for Ivy + UC + UT-Austin (Typical Dream Big Student)

Platform combination: Common App + UC Application + Apply Texas → 3 systems in parallel

Case 2: Conservative Route + Public Resources (Typical ROI Student)

Platform combination: Common App + UC Application + Apply Texas

Case 3: Extreme STEM Route

Platform combination: Common App + UC + MIT Application + Apply Texas

9. Time Management Advice for Operating 4 Systems in Practice

Rule of thumb: For 15+ applications, students should spend at least 4 hours per day during the summer.

Converted: Across a 60-day summer, this means 5-6 hours per day of pure application work. That is why I repeatedly tell Dr. G. students: start in the summer after 11th grade. Do not wait until 12th grade begins.

10. Conclusion: The 4 Platforms Are Only Tools; Winning Requires Knowing How to Use Them

Over the past 15 years, I have seen too many parents assume that “U.S. applications = Common App.” Then in November, they discover that the UC deadline is 11/30, Apply Texas is 12/1, and Georgetown requires a separate registration on its own system. The result is panic and missed applications.

There is no good or bad among the four major platforms. The schools you apply to determine which systems you need to open.

My advice:

1. May of 11th grade: finalize a preliminary school list with your counselor and map it against the four platform categories
2. June of 11th grade: register for a demo Common App first to get familiar with the interface
3. 8/1: open all four systems, register, and enter basic information
4. Late August: align Activities + Honors consistently across all platforms (the same activity description cannot be written four different ways across four systems)
5. September: move fully into main essay + supplemental essay writing
6. Late October: check each school’s deadline against your Excel sheet every week

U.S. applications are an engineering project, not a bet on luck. Use the right platforms and the right timeline, and you will already be ahead of 50% of the competition.
