The Princeton Review DAT: Course Options, 20+ Score Guarantee, and Verdict [2026]

The Princeton Review is an academic prep giant known for high-intensity courses and bold score improvement guarantees. In the dental admissions space, its premier offering is the DAT 20+ program, which promises that qualifying students will earn an Academic Average (AA) of at least 20 on the official exam.

With dental school admissions growing more competitive every application cycle, achieving a 20 or higher is the benchmark for securing multiple interviews. But at a price point reaching between $999 and $1,899, is The Princeton Review DAT worth the investment?

This review examines course features, live instruction quality, practice test realism, guarantee rules, and how it measures up against rival prep options in 2026.

Key Takeaways

• The Princeton Review's flagship course is the DAT 20+, offering 60 hours of live instruction led by multiple subject-specific specialists.
• The program includes four full-length practice tests proctored online under strict timed conditions, plus thousands of standalone practice questions.
• The 20+ Academic Average score guarantee provides a refund or free retake if you meet all qualifying study requirements and miss the score.
• Pricing is at the top of the market, ranging from $999 for self-paced access to $1,899 for live instruction courses.
• This course is best suited for applicants with high budgets who want structured, instructor-led drilling and score accountability.

What You Get with The Princeton Review DAT

The Princeton Review provides an all-inclusive prep package combining live teaching, printed manuals, online question modules, and proctored testing.

The DAT 20+ Guarantee: How It Works

The defining selling point of The Princeton Review is its score guarantee. An Academic Average of 20 places a test taker in roughly the 75th to 80th percentile nationally, making them a competitive candidate at most dental programs.

The Princeton Review offers a money-back refund on course fees if you take the DAT 20+ course and do not score at least 20 on the official exam. However, you must pay attention to the qualification fine print:

1. Starting Baseline: You must have a verified starting baseline score of at least 17 on an official DAT or a designated proctored diagnostic test.
2. Attendance: You must attend all 60 hours of scheduled live classes without missing sessions.
3. Homework Completion: You must complete 100% of assigned homework, problem sets, and diagnostic exams before test day.
4. Testing Timeline: You must sit for your official DAT within a specified window after completing the course.

If you meet all the criteria and your official score report shows an Academic Average under 20, you can claim a refund or repeat the course at no charge. The guarantee shows confidence in their curriculum, but requires total dedication throughout the program.

Live Instruction and Subject Specialists

Unlike many courses that use a single generalist instructor to cover every test area, The Princeton Review uses a multi-instructor model. You may have one specialist for Biology, another for General and Organic Chemistry, and a third teacher for Perceptual Ability and Quantitative Reasoning.

This structure ensures that the person explaining organic mechanisms or complex probability problems specializes in that exact field. The 60 hours of live instruction follow a dedicated subject breakdown:

• Biology: 15 hours
• General Chemistry: 12.5 hours
• Organic Chemistry: 10 hours
• Perceptual Ability: 7.5 hours
• Reading Comprehension: 7.5 hours
• Quantitative Reasoning: 7.5 hours

During these interactive sessions, instructors walk through fundamental concept reviews, demonstrate pacing tactics, and show how to dissect ambiguous question stems.

Question Quality and Proctored Practice Tests

The Princeton Review includes four full-length practice tests that are proctored online. You sit at your computer with a timed testing window that mimics the strict breaks and countdown clocks of the Prometric testing facility.

The questions are written to reflect official test specifications:

• Natural Sciences: Covers foundational cellular biology, physiological systems, chemical equilibrium, thermodynamics, reaction kinetics, and synthesis roadmaps.
• Perceptual Ability: Provides strategies for view recognition, angle discrimination, cube counting, and 3D folding.
• Reading Comprehension: Long passages with associated inference, tone, and main-idea questions.
• Quantitative Reasoning: Standard algebra, geometry, statistics, and word problem calculations.

The questions in the online portal are challenging and realistic. However, the online user interface feels slightly dated compared to modern software-first platforms, and the platform lacks dynamic, randomized PAT question generators.

Course Books and Materials

When you enroll in a live course, The Princeton Review ships physical textbooks to your home. These include:

• The DAT Review Manual (comprehensive science, PAT, and math review)
• The DAT In-Class Workbook (used for live class exercises and instructor problem-solving)

These books are detailed, well-organized, and filled with clear summary tables. Having printed materials is useful for students who want to study away from computer screens or do late-night content reviews without eye strain.

Course Pricing Options (2026)

The Princeton Review is one of the most expensive DAT prep options:

The company frequently runs promotional discounts ranging from $100 to $300 off during major academic registration periods.

Strengths and Limitations

Strengths

• High-stakes score guarantee: The 20+ Academic Average guarantee gives students a clear benchmark and security for their financial investment.
• Subject-matter specialists: Multiple instructors ensure that each topic is taught by an expert in that discipline.
• Proctored exam simulations: Four full-length proctored tests teach test pacing and combat exam anxiety.
• Substantial live hours: 60 hours of direct instruction provides deep concept coverage.
• Comprehensive physical books: High-quality review manuals make offline study practical and thorough.

Limitations

• Premium price: At nearly $1,900 for the live program, it is out of reach for budget-conscious students.
• Rigid qualification rules: The requirements to maintain the score guarantee are extensive and easy to void if you miss a single assignment.
• Lacks unlimited PAT generators: Static practice sets make it possible to run out of fresh spatial problems.
• Heavy time commitment: 60 classroom hours plus homework requires 20 to 30 hours per week of study time.

Comparison with Alternative DAT Courses

Before committing to The Princeton Review, consider how it stacks up against other prep paths:

• For modern, software-based self-study: DAT Booster offers over 11,200 practice questions, 60+ full-length practice tests, and unlimited PAT generators for just $299. It provides far more raw practice at a fraction of the cost.
• For traditional classroom learning at a lower price: Kaplan DAT provides live online classes with dual instructors starting around $999 to $1,299, offering a slightly more affordable structured classroom experience.
• For hard problem drills in chemistry: DAT Destroyer is a classic supplementary book set for students who want rigorous paper problem solving.

The Verdict

The Princeton Review DAT 20+ course is an intensive, high-yield program built for students who need live guidance, expert instruction, and the peace of mind that comes with a score guarantee. If you enter with a solid 17+ baseline, have the budget, and can commit to attending every class and finishing all assignments, the structured curriculum can reliably push your score past the 20 threshold.

However, if you are a disciplined self-studier who does not need mandatory classroom meetings, online platforms like DAT Booster deliver more practice tests, better PAT generators, and modern learning tools for thousands of dollars less.
