  • Tutoring programs are those organizations that offer one-on-one and/or small group tutoring directly to students, either in-person, virtually, or through both modes of delivery. 
  • Technology platforms are technology platforms that facilitate tutoring programs.
  • Interventions offer materials (e.g., an instructional scope and sequence, placement assessment, progress monitoring tools) that are used by a tutoring program, but do not offer tutoring directly.  

This database is intended for Districts, States or nonprofits to identify potential tutoring partners, for potential tutors to identify potential employers and for tutoring organizations to have a clearer understanding of the landscape and to identify interventions that might be useful to their programs, if needed.

Please note that some of these programs are also listed on ProvenTutoring.org where you can find additional information on relevant research studies and costs.

Curvebreakers' program plan is designed to provide school solutions through courses, materials, and professional development for SAT/ACT exams and other standardized tests in an innovative, effective, and engaging style. Our mission is to even the playing field in the college admissions process by offering programs that focus exclusively on the subjects covered on college entrance exams and effective strategies for approaching each question type. 

To accomplish our mission, we continuously evaluate progress toward our goals by analyzing practice test results, engaging in formal and informal discussions with school administrators, and collecting student feedback through course surveys. We make adjustments to our curriculum where necessary to ensure that we are providing the most effective test prep services available. 

Curvebreakers only hires instructors with extensive teaching experience and compensates them at a higher rate than many of our competitors. Our instructors are multilingual, and when offering professional development to teaching staff, we utilize only the most experienced instructors who have attained the Master Trainer level. 

We offer several funding options, whether through school pay or parent pay, and we follow all relevant laws and regulations, including state licensing standards. We connect with the community and families by presenting at college nights, back-to-school nights, or any other school event. We conduct live and/or virtual sessions for students, parents, and faculty on various college prep-related topics. 

Curvebreakers offers standard signature courses of 18 hours of classroom instruction, supplemented with two proctored practice tests. Generally, the classroom instruction is divided into eight 2.25-hour sessions, and each practice test is 3.5 hours. However, based on student availability and/or specific student requirements, course length and sessions are customizable. 

Our school programs were developed by Master Trainers, each with over 15 years of experience in the test prep industry, and feature unique content proven to increase test scores. These programs include personalized homepages, 140-page course workbooks with customized curriculums, detailed course lesson plans, detailed homework assignments, practice tests with detailed diagnostic score reports, session notes emailed to parents, self-study video strategy courses, and instructional videos. 

In conclusion, Curvebreakers is committed to providing high-quality, effective test prep services that prepare students for college entrance exams. Our program plan includes rigorous evaluation methods, highly experienced instructors, unique content, customizable courses, and multiple funding options to ensure that we are meeting the needs of all students and families.
