Are you seeing
the whole picture?

ADHD’s myriad symptomatology and co-occurring conditions can delay and complicate assessment, and it may make intervention and regular follow-up difficult.
There’s more
to the story

Whether it’s time constraints, accuracy,
quantifying severity, collaboration, inclusivity, fairness, or informing intervention, the challenges you face on a day-to-day basis solidify the need for convenient, comprehensive, and credible ADHD assessment.
Unlock their
potential

For some children, realizing their potential is just a matter of time. But for others, it can be obscured, even hidden behind the complexities of a disorder like ADHD.

Big picture.
Bigger opportunity.
Comprehensive assessment helps you see beyond the hallmark features of ADHD to provide a highly relevant and meaningful assessment of symptoms, impairments, and common co-occurring conditions providing children and adolescents the greatest opportunity to succeed.

Inclusivity meets
Innovation.
We want to make the world a more inclusive and fairer place to live. By collaborating with experts and researching the needs of both providers and children and adolescents, Conners 4™ is more relevant than ever.

Keeping it real.
To address challenges faced by psychologists during the assessment process, our tools must solve not only for complexity of ADHD and accuracy of diagnosis, but also for challenges associated with the day-to-day reality of time pressures, quantification of severity, collaboration, fairness, inclusivity, and informing intervention.

Perspective is
everything.
MHS continues to build on a legacy of continuous, evidence-based improvement in ADHD assessment.
Leveraging our human-centric, data-driven approach, and ongoing research, we provide comprehensive ADHD assessment tools with a unique focus on inclusivity and fairness.
