The most improvement in the least amount of review time™

Our Story. Our Founders. Our Advisors. Our Team.

Our Story

Jumpstart Test Prep began with one educator, Dot McClendon, and her passion to help students prepare for and perform better on the ACT® exam. She accomplished that for the daughter of Jumpstart’s co-founder and CEO, Sha Walker. After having taken the exam six times using other preparation methods, Morgan Walker dramatically improved her ACT® score after completing Dot’s brief classroom review of content tested, tips, strategies, and timed practices.

Dot’s knowledge and expertise in this area is legendary. She has dedicated more than fifty-five years to teaching and has received many awards - the most prestigious was being inducted into the STAR Teacher Hall of Fame resulting from being selected as STAR Teacher 19 years by students at three different schools.

After a lifetime of perfecting and refining her unique approach, Dot’s desire to pass along this knowledge to help students everywhere achieve the most improvement in the least amount of review was joined by many other Mississippi teacher experts and and has grown to now include the WorkKeys Job Skills assessment and End-of-Course exams required for graduation - all made available to any classroom online. Jumpstart Test Prep has now helped deliver dramatic exam improvements for tens of thousands of students. Jumpstart’s proven, guided review and assessments are being utilized in the classroom by educators in hundreds of high schools across seven states and students around breakfast tables and living room couches across the country.

Our Founders

  • Dot McClendon, Co-Founder

    Dot McClendon is first and foremost a people person. She has taught science and math for 56 years. She also serves as pastor of Homeseekers Bible Church in Wesson, MS. She is the primary author of the teaching modules in Jumpstart and has found its unique approach helps students of all academic ability levels stay fully engaged and gain the most improvement in the shortest time. She has mastered a technique of explaining difficult content in a way that every student can follow and understand. Score improvements by her students have led to acceptances into major universities accompanied by financial scholarships, which has opened the door to higher learning for many who would have never been accepted or able to afford college on their own.

    Like many educators, Dot’s passion for teaching was ignited by “seeing the light come on in a student’s eyes,” the exuberant moment when a student finally understands the material. This passion led to helping students prepare for the ACT® through private tutoring and live classroom events. After more than 40 years of tutoring dedication, few professionals are as qualified to provide exam preparation as Dot.

    Dot has received numerous school, community, district, and state awards through the years, but says her best award comes when a student says, “I raised my score!” She is humbled and honored to have been selected nineteen years through the STAR teacher program, wherein the top ACT scorer in a school selects his/her most influential teacher. She has been inducted into the STAR Teacher Hall-of-Fame and recognized as one of the top five educators in the Mississippi Teacher of the Year program. Through Jumpstart Test Prep, her legacy of helping students will remain intact and allow many others the benefit of her proven approach.

    Dot received her Master of Science degree in both chemistry and biological sciences from the University of Mississippi and her Bachelor of Science degree in chemistry with a minor in biological sciences from Mississippi College. A lifelong educator, Dot has taught at Copiah-Lincoln Community College, Brookhaven High School, and West Lincoln High School and recently retired as "teacher of the year" at the Mississippi School of the Arts. She is certified to teach chemistry, physics, biological sciences, and mathematics. Dot was married 26 years before becoming a widow. She reared two daughters and a godson, and she enjoys four grandchildren. She resides in Brookhaven, MS.

  • Sha Walker, Co-Founder & CEO

    Sha Walker, Co-Founder & CEO of Jumpstart Test Prep was searching for a proven, unique approach to improve ACT test scores. He learned of Dot McClendon’s ACT expertise and renowned preparation method firsthand after his daughter’s seventh try using other books and resources while scoring 20, 20, 24, 24, 23, 24, and 23 on those attempts. After only 16 hours of preparation, Jumpstart ACT delivered a dramatic improvement on her final attempt, a score of 27, thereby saving around one-third in tuition with an academic scholarship.

    In 2016, Sha began the mission of creating an online, on-demand delivery of Dot’s 40 years of test preparation experience and proven techniques to the millions of students attempting college readiness, high school equivalency, educator certification, and workforce certification assessments as well as Algebra 1 proficiently and understanding.

    At Jumpstart Test Prep, Sha leads all aspects of the start-up. Sha taps all of the skills he acquired early in his career at L.M. Berry Company and later at Hurst Review Services where he held senior roles.

    Sha received his Bachelor of Business Administration in 1990 from Mississippi State University, and received his Master of Business Administration in 2017 from Millsaps College. He worked for nearly 15 years at the L.M. Berry Company, a Bellsouth company that later became an AT&T company. Sha served in roles of sales and management before joining Hurst Review Services in 2008 as Chief Marketing Officer, and later served as Vice President of Sales and Marketing. Hurst Review Services offers the nation’s premier review course to assist nursing students preparing for the NCLEX® licensure examination. During Sha’s tenure, the company realized a revenue increase of over 800%, growing from a southeast regional footprint to providing services in all 50 states and Canada.

    Sha has been married 27 years, has two children, and still resides in the Brookhaven community. He has served as adjunct professor of business at Copiah Lincoln Junior College and past president of the Brookhaven Lincoln County Chamber of Commerce. He is also a member and past president of the Brookhaven Servitium Civic Club and is a congregant at Johnson Grove Church of Christ.

The students who were part of choosing her for this honor had been through several semesters of Calculus with Renee during one of the hardest times in education – the COVID pandemic.
