National Reading Diagnostics Institute & Keys Learning


In two easy steps, we will find the cause of your child’s reading comprehension, memory, or learning problem and fix it in the shortest possible time.

Starting today you can raise your child’s grades, test scores, and reading levels, while building self-esteem, confidence, motivation, and focus. Don’t let you or your child suffer one more day in the cycle of failure but turn it quickly into the confidence and joy of success.

You know your child is bright, but you still cannot figure out why he or she  is struggling in school with reading, comprehension, memory, grades, test scores, study and test-taking, or learning any subject. You may have already spent a great amount of time and money getting help either from a tutor, tutoring center, or the school, but see no improvements. In fact, with each passing year, your child’s grades, reading, and test scores are getting lower. You are lost and helpless, and don’t know where to turn. You can finally breathe a sigh of relief, as you have finally come to the right place.

Here are some comments from parents:

“I have worked with National Reading Diagnostic Institute for over a year now. I have seen amazing results for my son. Not only has his reading level improved dramatically, but his confidence and enthusiasm are through the roof. I recommend Ricki Linksman and National Reading Diagnostics Institute to anyone who wants to give their child an advantage.”  –Stefanie Synal

“My son has only been with Ricki Linksman a short time, but already we have seen improved results in his SRA tests, and overall academics. In fact, he made the honor roll!!  I appreciate the fact she is able to see how he best comprehends his reading material and incorporates the best plan for him. She has a wonderful disposition working with students and she is able to communicate and convey her teaching in a concise and effective way. We are very happy to see his overall comprehension improve and especially his confidence. Thank you!”  –Liz Zurek

We know what you’re going through because thousands of parents who have come to us in person or emailed us for help from all over the world have felt just like you did. When they discovered how we solved their child’s reading or learning problem and fixed it quickly, they wished they had found us sooner. In fact, many wished they had known about us years before. But it’s never too late to get instant help for your child. Whether he or she is in elementary, middle, or high school, or even in college, we can diagnose why your child is having a problem with reading, content-area subjects, or test-taking, and fix it quickly.

“I believe no child should experience the frustration, low self-esteem, and lack of confidence that comes with school failure. Our commitment is to help every child or teen soar from failure to success immediately, without spending one more day in a state of helplessness. That is what makes us different from all other tutoring centers to which you may have gone  already–our goal is to solve the problem and fix it in the shortest time–not prolong the time your child needs help. We turn your child into an independent learner so he or she will succeed without tutoring help any more for years to come.”                                                                                                          –Ricki Linksman, Founder

We save parents the time and money you might have normally spent on getting help, because our goal is to fix the problem in the shortest time. Nothing gives us greater joy than to see the pain on the face of a frustrated parent and child turn into the smiles of success, even in the first session.

Studies have shown that our award-winning techniques have taken entire schools (K-12) from 88-99% of all students raising their reading levels from two to five grade levels above their age in 8 months or less. At our National Reading Diagnostics Institute parent-child tutoring center, we have seen those results often within a few months. We have even taken schools where 2/3 of the students were not meeting state standards in reading to 2/3 meeting and exceeding within less than one school year. This includes all students–regular ed, gifted, special ed, ADHD or ADD, Title 1,  Dyslexia, or Remedial Reading, or ELL, ESL, English as a Second Language, or Bilingual.

Our Approach at NRDI

What makes us different is we use brain research to find your child’s own unique way of learning combined with a reading diagnosis. You know your child is struggling. You may even see your child’s reading test scores are lower than what you think they should be. But what no one tells you is why that is happening. We specialize in giving your child a reading diagnosis assessment and learning assessment to find the cause of his or her problem and a way to fix it in the shortest possible time.

Each tutoring/coaching lesson is targeted to fix whatever skills your child needs, whether in reading, reading comprehension, phonics, vocabulary, test-taking, note-taking, study skills, writing, spelling, or content-area subjects. Lessons are taught in a way that matches your child’s best learning and brain style. Whether your child is a visual, auditory, tactile, or kinesthetic, whether left or right brain learner, or a combination, we give you lifelong techniques your child can use now, or through his or her entire school career and in life. Find your child’s unique and best way of learning today so he or she can learn any subject in the way he or she learns the best and fastest.

About NRDI and What We Do 

National Reading Diagnostics Institute and Keys Learning, headquartered in Naperville, Illinois, was founded and directed by Ricki Linksman since 1993. We specialize in reading diagnostic testing and learning style/brain style testing (pre-K, K-12, college and adult) to help each child or teen raise reading levels, grades, and test scores to reach grade level and beyond in reading and learning in the shortest possible time. After diagnosing the student’s reading and their fastest way of learning, we provide an individual prescriptive plan on how to solve any problem or attain the parents’ and student’s goal.

We then offer caring, one-on-one private coaching/tutoring by our highly trained, caring teachers to teach the needed skills in your child or teen’s best learning style and brain style. Through our parent-child one-on-one sessions for K-8, or one-on-one for high school (parents are invited to the sessions with their teens also, if they wish), or our small personalized group classes, we help students reach success rapidly teaching them how to learn in their own style.

We offer services all year, with tutoring and coaching after-school and during the summer. We offer flexible schedules to meet your family’s busy lives. There is no contract to sign–you can start when you want and continue as you wish, with no long-term financial commitments on your part.

After reaching their goals with us, our students continue to use our methods to learn independently as top students for the rest of their lives. We also help athletes use our Superlinks Sports accelerated learning methods to excel in their sport, maintain their academic grades, and improve scores on the ACT or SAT through their kinesthetic or other learning style. We also have a reading and learning program for kinesthetic and tactile learners, whether diagnosed or suspected of having ADHD or ADD, or who are kids who just learn best by moving!

Our award-winning proven methods are recognized throughout the world. Public and private schools throughout the United States and other countries have used the techniques taught by founder-director, Ricki Linksman, to take failing schools to superior schools to meet their state standards in reading within less than a school year. Institutions such as Huntington Learning Centers, Kaplan On-line University, and private tutoring centers throughout the world have also licensed our learning materials. Companies such as Lucent Technology, 3M, large financial institutions and tech companies, besides many universities have used Ricki Linksman’s techniques for training, instruction, or increasing productivity by better communicating to customers, clients, trainees, or employees.

Besides the live testing and tutoring/coaching in Naperville, Illinois (western suburbs of Chicago) numerous resources are available for parents and teachers, such as books, ebooks, videos, digital products, and two world-renowned Internet reading and learning software programs: Keys to Reading Success online reading program for parents and schools, and the Superlinks to Accelerated Learning assessments for at-home or schools.

“I have known and worked with Ricki Linksman for over fifteen years. I still remember today what I heard Ricki say so many years ago; ‘Kids learn differently, their learning style is as unique as they are.’ Ricki explained her program which could be implemented quickly for children who were struggling in reading. As a teacher I had immediate help for a problem that frustrated me to no end. I used the program in my classroom and had success. Using lessons and materials that address different learning styles, Ricki’s methods take students who are struggling in the classroom and teaches them how to succeed. Whether you’re in a classroom setting as I was, or a parent who is trying to help their struggling child, Ricki’s methods work. As a teacher and a tutor, I have seen first hand how students who first felt defeated because they learn differently, go from being D students to A or B students. Whether your child is just learning to read, or reads the words but is not comprehending, this program can help. As a classroom teacher and tutor who used the techniques from the National Reading Diagnostics Institute, I can honestly say a student who walked through the door on the first day with their head down was a far cry from the student who, after a period of instruction, left with their head held high, their confidence level boosted, and their reading/grades greatly improved. When you see the excitement of a child who can finally read and understand what he has read, as Master Card says, the feeling is priceless.”   –Sharon Dye
