All three providers offer some form of score guarantee — but the details vary dramatically. Here's what's actually promised, and what happens if you don't hit the target.
If you're in the Houston metro area, local presence can make a real difference. Here's how each provider serves the region.
Headquartered in Sugar Land, TX (13100 Southwest Freeway). TestMasters was founded in Houston and has deep roots here. Multiple in-person class schedules run throughout the year across Houston-area locations. Local phone support at (281) 276-7777. Students can also attend free weekly extra-help tutorials at local venues.
Also available in-person across Texas: Dallas, Austin, San Antonio, and more.
Kaplan offers in-person SAT prep in select cities. Houston availability varies by season; check kaptest.com for current schedules. The Live Online course is always available. No dedicated Houston office — support is via the national 1-800-KAP-TEST line.

What can you realistically expect from each program? Here's what publicly available data and student feedback tell us.
The sub-1% retake rate is a strong signal: the vast majority of students hit the 200-point improvement threshold without needing a second pass.
Kaplan's internal 2022 survey of 557 students showed their NPS exceeding two unnamed competitors. No aggregate score-increase figure is published.
Princeton Review spotlights students who achieved 1400+ scores with 140–220 point improvements. Aggregate class-wide averages are not published.
