"Having held diverse roles in education, including literacy consultant, coordinator, and literacy teacher, I firmly believe that the most effective improvement comes from precision teaching, grounded in a deep understanding of the learner. Lyn Sharratt offers the strategic CLARITY that educators require to implement this essential practice with fidelity. In her latest book, Lyn continues to bring highly impactful insights to educators to enhance students' learning outcomes. From start to finish, the case studies and high-impact strategies in this book are practical, realistic, and immediately applicable. Sharratt’s extraordinary contributions shine throughout these pages, reflecting her remarkable work as a teacher, leader, author, researcher—and mother, the most meaningful role of all. She is a role model for our family and to me."

Michelle Sharratt, Literacy Teacher, Ontario, Canada

"Clarity of purpose, possibilities, and outcomes have been hallmarks of the curriculum practice and educational leadership of Dr. Sharratt's work for decades in education internationally. For her, evidence mattered. Capacity-building mattered. Achieving equitable outcomes mattered. Demonstrating the true potential of diversity on all its faces mattered. Generations of educators who have a strong commitment to the realization of human potential in all its forms will welcome this book not only as the culminating thoughts of Dr. Sharratt’s lifetime in education, but as a prescription for future practice. Dr. Sharratt provides us with a pathway to realizing our potential to reach the Ultima Thule of education. What is authentic about her writings is that she has done the work and has the results to show. Dr. Sharratt’s enduring legacy will be her impact, through firsthand experience with policy instruments and tools, on changing the trajectory of educational outcomes in school districts globally, characterized by her persistence and tenacity in “putting FACES on the data” – and taking action!"

Dr. Avis Glaze, Author, Researcher, International Education Adviser and Former Ontario Education Commissioner

"Reading the CENT case study again, it all has become very real in terms of what has been achieved, and I am very grateful for your contribution and support, Lyn. There truly is a sense of progress and momentum here at CENT. I am convinced that your partnership with us has been a key driver of this, and your regular presence has compelled our accountability in getting on with our focused CLARITY work."

Paul Greaves, Director of Education, CENT, Australia

"Working with Lyn during the past three decades has provided me an opportunity to witness true dedication to the well-being of all students. The belief that “all students can achieve to high standards, given sufficient time and opportunity,” has also applied to her relationships with professional colleagues in classrooms and in leadership positions. "The caring attitude that extends to school staff, district leadership, and to all the important aspects of working with children of all ages is evident again in her latest book. Lyn understands how theory, research and practical application merge to create effective learning environments in any jurisdiction and in every school. Learning matters, leadership matters, and people matter for Lyn. This most recent publication continues the high standard that she sets for herself in everything she does. The thread of Lyn-CLARITY through the years has always been evident and is explicit in this publication. That CLARITY means true dedication, high levels of passion for the needs of students, and a deep love of learning. Lyn is a very real gift to the education community."

Todd Wright, Administrator of Information Communication Technology, eLearning and Learning Resource Services, York Region District School Board, Canada

"The work you have done has facilitated transformational impact in any school that embraces CLARITY wholeheartedly. The majority of teachers who enter our profession genuinely want to make a difference; they just don't always have an understanding of how to achieve this impact consistently. Neither do school communities -- the silo approach does not work -- and you have shown anyone who is prepared to listen how it's done. Words are paltry, and I have said nothing to you that you have not been told a million times over (and more eloquently, I am certain). I just wanted to thank you because being around you and your Professional Learning sessions have been uplifting."

Zena Dabaja, Director, Educational Leadership, Canterbury Principals Network, Metropolitan South Directorate, New South Wales Department of Education, Australia

"[Our] school was privileged to be introduced to Lyn Sharratt’s work on CLARITY through attending a leadership conference delivered by Dr. Sharratt whilst in Sydney, Australia. Our leadership team identified the relevance and impact this work could have in our specialized setting."

Jenny Zagas, Principal, and Wendy Du Plessis, Assistant Principal, Lucas Gardens Primary School, New South Wales, Australia

"The first year of our learning journey with Dr. Lyn Sharratt has been powerful. CLARITY has given us practical tools—Data Walls, Learning Walks and Talks, and the 14 Parameters—that helped leaders and teachers move from theory to action. This work has strengthened collaboration, sharpened assessment practices, and built confidence in using evidence to improve student learning. Lyn’s ability to adapt her global expertise to our Abbotsford context made the experience meaningful and impactful. For those involved, CLARITY has been more than Professional Learning—it’s a catalyst for focused, intentional improvement."

Tracy Krys, Director of Instruction – Curriculum, Abbotsford School District, Canada

"As a network of schools, we have been reinvigorated to focus on Assessment Literacy and Explicit Instruction as the right work. Our partnership with Lyn has affirmed our intention as a Network to work collaboratively to implement CLARITY with fidelity to enhance and strengthen the quality of teacher instruction, student progress, and achievement for all students in our Network. Our shared vision for improvement is reflected in [our] Theory of Action, we have developed our operating norms and protocols for collaborative engagement, “CLARITY buddies” have been formed, and the Gradual Release of Responsibility becomes the specificity for each school because of the earlier learning and work. Accountability through professional relationships and connections between schools is maintained by [having] time to do the work and [having] access to a Knowledgeable Other. Learning and sharing across schools within the network and across the Regional North and West Public School Directorate has been supported by a deep understanding and implementation of the 14 Parameters and the Assessment Waterfall Chart, aligned with strong educational leadership focused on quality assessment and quality instruction. Our students have the benefit of our collaborative expertise in working with Lyn."

Debbie-Lee Hughes, Director, Educational Leadership, Lithgow Principals Network, Wiradjuri Country, Regional North and West Directorate, New South Wales, Australia

"You are a global treasure. People want to hear what you, as one of our most admired thought leaders, have to say. You have so much to offer the world!"

Dr. Avis Glaze, International Education Adviser and Former Ontario Education Commissioner

"Dr. Lyn Sharratt’s work has had a profound and sustained impact on my leadership practice and on the way schools approach whole-school improvement. Her research-based frameworks, particularly the 14 Parameters and the CLARITY Learning Suite, have provided us with a shared language for improvement that is both intellectually rigorous and deeply practical. "As a school leader, Dr. Sharratt’s work has strengthened my capacity to lead with clarity, coherence, and intentionality. It has sharpened focus on evidence- informed decision making, aligned improvement efforts across leadership and classroom practice, and ensures that student learning is always at the center of every conversation. The emphasis on collective efficacy, high expectations, and shared understanding has been instrumental in moving our work from compliance to genuine, sustained improvement. "At a whole-school level, the impact has been transformational. Teachers and leaders now engage in purposeful professional dialogue grounded in evidence of student learning. Instructional practices are more consistent, feedback is more precise, and improvement initiatives are no longer fragmented but are strategically aligned. Dr Sharratt’s work has empowered our staff to see themselves as leaders of learning and has built a culture of shared responsibility, accountability, and continuous growth. "Most importantly, the clarity and coherence her work brings has translated into improved outcomes for students. Dr. Lyn Sharratt’s contribution to educational leadership extends well beyond theory; it provides a practical, scalable, and deeply human approach to leading schools in complex contexts. I strongly endorse her work and its capacity to drive meaningful, sustainable whole-school improvement."

Lauren Phillips, Principal, Macarthur School, Aspect Education, Australia

"Data need to drive whole-school decision making, and observations of practice are critical for school leaders to understand the Professional Learning required to upskill individual and collective staff capacity. The Upper Hunter Network, NSW, Australia, without a doubt, over a two-year journey with Dr. Lyn Sharratt, has been provided with the theory and practical implementation skills to bring these to life. Over this period, our focus on Parameters 1, 6, and 14 in year 1 and Parameters 3 and 13 in year 2 has provided the blueprint for success. Having a common understanding and approach through CLARITY work has ignited a philosophy of “using the group to grow the group” across our Network. I now enter schools and see data informing school direction, teachers who are enjoying their teaching more because they know their students’ learning better, and students' learning supported by visible and explicit Learning Intentions and Success Criteria. Pleasingly, we are already seeing green shoots in student outcomes as a result of our collaboration with Lyn."

Sean Andrews, Director, Educational Leadership, Upper Hunter Network Public Schools, Regional North and West Directorate, New South Wales, Australia

"Your work with us has truly anchored us… I believe that it is that base of the 14 Parameters that has saved the situation in the last few years because we managed to institutionalize it to a certain extent, although the staff is quite new now and may not be able to articulate all of that. The “in-and-out” people were not there long enough to change that, thankfully. But things are looking up now so it should be a good new year. I truly believe that participating in the CLARITY Learning Suite lifted my colleagues and brought them back to that anchor of the 14 Parameters because most of them lived it as coaches or Principals and know its power. In my humble view, they just need to become intentional about it. The world needs you and your epic work more than ever!!"

Diane Ouellette, Prince Edward Island, Canada

"I have been teaching since 2004, but when I read your book CLARITY in 2019 and listened to it again on Audible in 2020, it transformed my leadership and teaching. You brought back the joy of teaching and leading for me. Over the years, my school has been a very small, culturally diverse government public school in southwestern Sydney with approximately 214 students. Our community is transient and considered to be in a very low socioeconomic area. I am grateful for your commitment to learning, teaching, and leading. Over the last two years, I have been embedding the 14 Parameters in our teaching and learning culture. Last year, our NAPLAN results were exceptional in literacy and numeracy. I was asked by our Director of Educational Leadership to share with our network of schools how we achieved such strong results at the school I work in. I genuinely believe your work influenced this. I continue to recommend your book to other educators, and this year I purchased copies for our executive team to sustain this practice and build teacher capability."

Lili D’Cruz, Assistant Principal, New South Wales, Australia

"Lyn, your work in Wales is making a positive and significant difference to teachers and the young people they teach. Thank you."

Dr. Alma Harris, Wales

"As an educational leader, I have had the privilege of working closely with Dr. Lyn Sharratt through her Clarity work, and her leadership combines intellectual rigor with practical relevance for principals and instructional leaders. Lyn brings precision to the use of data, assessment, and instruction, supporting leaders to make informed, evidence-based decisions about teaching and learning. Her work in schools reflects a coherent leadership approach that builds shared understanding, professional trust, and a sustained focus on practices that improve student outcomes. In my leadership roles, I draw on Lyn’s expertise to guide leadership teams through a focused improvement journey that leads to measurable gains in student achievement. Her work strengthens assessment literacy, sharpens instructional decision-making, and fosters a culture of precision and collective efficacy. Lyn’s leadership is a powerful model for educational leaders committed to clarity, precision, and lasting impact."

Anastasia Hendry, Principal, Consultant and Educational Leader, Australia

"Lyn, you are a difference-maker! I’ve seen lots of speakers and have worked with lots of people over the years. You and Bev are the two best I’ve seen anywhere in the world!!! And both have made a big influence on me personally. I’m beyond looking good, it’s all about learning for kids!"

Mike Borgfjord, Chief Superintendent/CEO, Edmonton, Alberta, Canada

"I have watched with great admiration, over many years, Lyn’s influence on educational leadership, both in Australia and internationally. Lyn has an exceptional gift for translating rigorous research into practical, actionable guidance for leaders and teachers. Her enduring commitment to “putting FACES on the data” and to achieving CLARITY in learning, teaching, and leading has reshaped professional conversations and practice across systems and schools. Through her research and its practical application, Lyn has provided a roadmap that continues to drive equity and excellence at every level of education. Lyn received well-deserved recognition with the 2025 ACEL Presidential Citation. This citation not only celebrated a remarkable body of work, but also honored a legacy that has transformed classrooms, empowered leaders, and improved outcomes for countless students. Significantly, Lyn’s impact is enduring, and this recognition couldn’t be more deserving."

Dr. Barbara Watterston, former CEO, ACEL, 2020–2025
