We’re charting new territories and shaping the future of MHS with several exciting developments and initiatives underway. It’s with great pride that I share more about the successful integration of two exceptional organizations into the MHS family.

Making our communities safer
Northern Ireland-based software company Core Systems (NI) Ltd. is a solutions provider accelerating positive change in the justice system globally through innovative technology.

Core specializes in interactive technology solutions supporting justice-involved individuals. Their solutions assist and enable individuals in custody, on probation, and serving community sentences to take an active role in transitioning back into the community successfully. Our acquisition of Core aligns with MHS’ collaborative, multi-party approach to advancing equity, improving access to justice, and increasing systemic efficiency for everyone impacted by the justice system.

We are also pleased to announce the acquisition of UK-based People Technologies Ltd., the premier supplier of automated solutions to the aviation industry for the selection of pilots and air traffic controllers.People Tech’s products are supported by two decades of scientific research and an extensive evidence base for predicting success in military and civilian training programs. Their products have been deployed in 20 countries across Europe, Asia, South America, North and East Africa, and the Middle East and are currently available in 11 languages. Our acquisition of People Tech aligns with our commitment to providing our clients with the highest standard of evidence-based assessments and solutions, ensuring accuracy and reliability during recruitment, and supporting organizations to succeed.We are innovating these novel solutions and are excited to share more developments in the future.

Creating equitable opportunities
With over 40 years of experience in developing tests and rating scales for the education market, we have been honored to collaborate with educators, researchers, and practitioners to improve the equitable identification of students with high potential across ever-increasingly diverse communities.

Learn more about the Naglieri General Ability Tests™. These tests measure general intellectual ability across verbal, nonverbal, and quantitative content areas. The Naglieri General Ability Tests™ were carefully designed to remove cultural influences, allow students to solve problems regardless of the language they speak, and
significantly reduce the amount of formal knowledge required so that the tests measure how well students “think,” rather than what students “know.”

We’re also excited to announce the arrival of the Gifted Rating Scales™ Second Edition (GRS™ 2). The original Gifted Rating Scales have been trusted worldwide to identify children for gifted and talented educational programs for decades. The GRS 2 was designed to take a more comprehensive multidimensional approach to identifying gifted students, providing a richer, more nuanced understanding of a student’s abilities. The GRS 2 supports a well-rounded gifted assessment process by incorporating insights from various perspectives.

Moving forward
Looking ahead, MHS is poised for extraordinary growth and transformative impact. We’re forging new pathways and pioneering innovative solutions that address critical needs worldwide. Our commitment to advancing equity, enhancing access to justice, and delivering evidence-based solutions remains unwavering.

As we embark on this exciting journey, we are thrilled to introduce our new CEO, John Clarke, who will lead MHS into a future of collaboration, innovation, and inclusive excellence. Together, we will continue to shape a brighter future where all can thrive. Thank you for joining us on this remarkable journey.

It’s been great connecting with so many loyal MHS customers over the years at conferences and meetings. Stay up to date with what I’m up to by joining me on LinkedIn.

John Clarke

Chief Executive Officer

At MHS, we strive to help create a world that is more empathetic, inclusive, and productive, complimenting fundamental shifts underway in how society supports and enables its members to live healthy, fulfilling lives —
justice reform and rehabilitation, inclusive healthcare and classrooms, cultivating empathy as a vital human skill for leaders in the hybrid workplace.

Our vision at MHS is clear, “human insight at your fingertips.” It’s this vision that embodies our dedication to unlocking human potential and empowering individuals to achieve their fullest capabilities.

We provide the tools and insights needed to support and elevate human potential. Our mission drives us to continually advance our science and research capabilities to foster growth. By supporting decision-making and improving outcomes, we help individuals and communities thrive and we are committed to positively impacting and enhancing the quality of life for everyone we serve.

Embracing digital evolution: A journey towards innovation and impact
Our transition from paper assessments to digital solutions marked a significant milestone for us. By developing industry-leading digital tools, we are laying a strong foundation for more robust solutions across all industries we serve. This digitization effort not only enhances the value, accessibility, and utility of our assessments but also enables more efficient real-time decision-making, crucial in scaling treatment, particularly in the healthcare market, where the demand for care often outpaces the availability of clinicians.

We have successfully navigated the complex landscape of data compliance and security, positioning our digital tools as viable solutions for some of the world’s largest healthcare providers. This accomplishment reflects our dedication to creating secure, compliant, robust digital platforms that meet the rigorous demands of modern healthcare environments. You can read more about our Digital Trust Framework here. Our digital transformation has opened new opportunities for us to provide solutions at scale. Through integrations and implementations, we offer unparalleled access to our scientifically backed solutions that integrate directly into electronic health record systems. This solution enhances clinical workflows by providing seamless, real-time insights, ultimately improving patient outcomes and operational efficiency. It also ensures that our tools are not simply digitized versions of paper assessments but advanced, secure, and compliant digital solutions that meet the high standards of the healthcare industry.

Our tools and solutions are underpinned by rigorous scientific research, ensuring their efficacy and reliability. We are leveraging tried-and-true measures and pioneering in new areas, such as our recent work in identifying and supporting gifted students from traditionally underrepresented groups. By leveraging world-class science to address current challenges, we’re creating better outcomes across all areas we operate in. This achievement is a testament to our commitment to innovation and excellence.

The Role of technology in rehabilitation and beyond
Investing in technology and novel solutions helps us support our communities by evolving our offerings. By aligning with the Risk-Needs-Responsivity (RNR) model, our solutions are designed to assess and address individuals’ specific risks and needs at various stages of the justice process. This model ensures that interventions are tailored to each individual’s risk level and personal needs, enhancing the effectiveness of rehabilitation efforts. Through advanced technology and data-driven insights, our Core Pathway solution provides a comprehensive approach to support individuals at every stage of their journey, promoting successful reintegration and breaking the cycle of recidivism. This targeted support is crucial in creating a more just and supportive community.

Empowering equity in education
MHS has been at the forefront of developing tests and rating scales for the education market for decades. The Naglieri General Ability Tests™ are a prime example of our commitment to fairness, equity, and inclusivity. Designed to remove cultural influences, the tests measure how well students “think” rather than what they “know.”

By using fair and inclusive assessment practices, educators can unlock new opportunities for these students and help them reach their full potential. As we continue to expand our offerings in the gifted and talented space, we remain committed to providing innovative and inclusive assessment tools that recognize and nurture the potential of every student.

Strategic innovation: Moving into talent selection and beyond
New products help drive innovation, and our teams fuel all that by bringing their diverse expertise and creative, collaborative problem-solving skills. We are expanding our talent portfolio to more completely embrace the entire employee lifecycle to provide a fulsome solution to organizations looking to select, grow, and promote their talent.

We now deliver comprehensive solutions across the entire talent management continuum, from selection and onboarding to development and succession. This holistic approach to servicing the employee journey is supported by developing new tools and forming innovative partnerships.

Finally, we would not be able to do what we do so well without our tremendous team MHS. Our culture embodies the nature of our business—caring for and supporting others is our mandate and, therefore, our culture. A common purpose connects us: doing well, doing good. This naturally drives us to attract individuals who are passionate about this purpose. Our innovation stems from this same place; By grounding everything we do in how we affect the lives of others; we foster an inherent drive to continually innovate. I look forward to seeing where this innovation fueled by compassion takes us next!
