  • 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.

In order to ensure that our students are receiving the best possible academic support, students take a variety of assessments. Before beginning tutoring services, students will take a diagnostic assessment so that we have an understanding of what areas the student has mastered and what areas the student needs to review. Our assessments are coded and aligned to Common Core Standards and specific state standards. As students begin tutoring with their assigned educator, they will frequently be presented with formative assessments to track their progress and understanding. At the end of each unit or topic, students will be presented with a summative assessment to ensure that the target areas have been mastered. These assessments may come in a variety of forms, such as projects, presentations, short quizzes, etc. All progress and data is tracked through our learning platform for both educators, parents, and administrators to keep track of. If we see that a student is not making the necessary progress, then we will reevaluate the case and create a new learning plan.

Tier One Learning Solutions was launched in Fall 2020 out of a sincere passion and need to educate children with integrity by providing an intervention-based tutorial service that goes beyond homework assistance. The idea was brought upon by frustrations and obstacles that my husband and I, both Certified Educators, encountered while teaching in various school districts in Texas.School districts classify students with academic deficits as Tier II and Tier III students performing below grade level in core subjects and school-wide assessments given at various times throughout the school year. Tier II and Tier III students are recommended for intervention-based tutorials during school hours but often do not receive these services consistently throughout the school year. Being former classroom teachers, we understand first-hand the need to provide intervention-based tutoring in schools; however, schools often do not have adequate staffing, the proper curriculum and additional educational materials to provide intervention-based tutoring. We have now made it our mission that every child will be a “Tier One Learner” by providing intervention-based tutoring in Reading and Math.
