ChalkTalk | Boosting Students Potentials | Mohannad Arbaji

For as little as 20 hours of ELA & math instruction time, teachers can use ChalkTalk to measurable gains in ELA & math learning outcomes. All students take a real official state test (such as the SAT or ACT) at the start and at the end of the academic year, with options to take it more times in between. This allows us to report improvement in terms of both proficiency and growth.

Below is a spotlight for some of our multi-year studies:

• ChalkTalk’s inaugural Global Impact Study comprises of nearly 20,000 students across 92 sites and 7 districts. On average, students enrolled in ChalkTalk gained +2.2 points on their ACT score. This is a 2x growth compared to the national average ACT score improvement (2.2 points vs 1.1 points) in only 29% of the time frame. It also found students enrolled in ChalkTalk who took the SAT achieved a +160 points average SAT score. This is a 2.4x growth compared to the national average SAT score improvement (160 points vs. 66 points) in just 27% of the time frame.

“I used ChalkTalk the first semester, and all my intensive students who failed the Florida test the first time took the test again that semester and 83% of them passed! ChalkTalk helped me do this,” says Pascale Lassegue, Intensive Reading Teacher, Felix Varela Senior High School, Miami-Dade Schools.

• Duval County Public Schools (Multi Year) is the 20th largest school district in the nation and the 6th largest school district in Florida. Students who used ChalkTalk improved their ACT scores by an average of 3.3 points – 3x more than national average score improvement and improved their SAT scores by an average of 56 points – 1.6x more than national average score improvement in only 27% of the time.

Caroline Portlock from Sandalwood High School wrote “I ran through ChalkTalk the first semester, and all my at-risk students took the state test [again] in Oct, Nov and Dec and 78% of them passed!!”

• Lake Nona High School (Multi Year) is part of Orange County Public Schools, the 11th largest school district in America. The school enrolls more than 3,000 students in grades 9-12, more than half of whom are low-income, and 70% minority. Throughout the years, students who used ChalkTalk saw an average 97-point improvement on the SAT which is 2.7x greater than the US national average in only 33% of the time.

Donielle Gregory, Vice Principal at Lake Nona High School says, “We’ve been trying to improve our graduation rates for years. This year, all we did was add ChalkTalk for 14 weeks and we raised our concordant test scores by 19%.”

• East Boston High School (Multi Year), the largest high school in the city of Boston, has an enrollment of 1,495 students, 59% of whom are economically disadvantaged and 86% of whom are non-white. Over the past four school years, students who used ChalkTalk saw an average 95-point improvement on the SAT, which is 1.4x greater than the US national average in only 23% of the time.
• Phoenix College Preparatory Academy (Multi Year), a public charter school located on the campus of Phoenix College in Arizona, offers high school students a chance to earn college credit as early as ninth grade. From 2020-22, students who used ChalkTalk saw an average 2.4-point improvement on the ACT which is 2.2x greater than the US national average in only 33% of the time.

“It [ChalkTalk] makes my life easier, and I want it to make other teachers’ life easier,” says Petra Abril, ELA & Math Special Education Director.

• Maui High School (Multi Year) is a public high school that’s part of Hawaii Department Of Education and is located in Kahului, Hawaii. It has a minority enrollment of 90. Over the past two school years, students who used ChalkTalk improved their ACT scores by an average of 2.5 points – 2.3x more than national average score improvement in only 31% of the time.

Expanding beyond the realm of high school state testing, ChalkTalk now offers the most widely-used and most highly-rated K-12 Math curricula on its platform: K-12 Eureka Math®  and Illustrative Math K–12™ Math. Responding to district feedback that they need an easy platform to roll out their rigorous adopted curricula, ChalkTalk created a platform that includes scheduling, daily lesson planning, instructional materials, standards-aligned grade-level practice, and real-time analytics. By analyzing data from assessments and instruction, ChalkTalk identifies students’ learning gaps and enables teachers to respond seamlessly.

With ChalkTalk, admins can run reports that identify which teachers’ edits to the materials and instructional strategies are causing higher levels of standards mastery for students. They can then recognize and celebrate those teachers publicly within ChalkTalk, as well as showcase those changes to other teachers in the district with a single click. Similarly, admins can use reports to identify which teachers are seeking additional help to support them targeted PD and instructional coaching within ChalkTalk.

ChalkTalk Founder and CEO Mohannad Arbaji said, “44% of K12 workers in the US say they ‘always’ or ‘very often’ feel burned out at work, outpacing all other industries nationally by more than half. We believe all teachers—regardless of experience, expertise, knowledge or success—deserve high quality coaching and we’re glad to be playing a role in that.” Below is a spotlight from one of our K-12 math district partners:

• Longview Independent School District: during longview’s summer program, 162 students completed 1,064 ChalkTalk sessions over the duration of 6 weeks where this was the only platform used for assessment & instruction. There were 44% more students with >80% mastery of grade-level Texas State Standards (TEKS) over the course of using ChalkTalk. Arbaji expressed “Marked year-over-year score gains in schools that apply ChalkTalk inspire our whole team in our mission of supporting educators.”
