Conners Family of Assessments

Why should the Conners Rating Scales be part of your ADHD assessment battery?

We recognise that obtaining a diagnosis can be a significant step for individuals to achieve understanding, support and to navigate positive outcomes.

Briefly, we have highlighted some key features of the Conners 'family' of assessments that have made it a globally recognised measure to help diagnose Attention deficit hyperactivity disorder (ADHD).


The importance of standardised assessments

Recommended in the NICE guidelines, the Conners Rating Scales are used in a number of comprehensive measures to assist in identifying, diagnosing and offering support or interventions for ADHD. 

Comprehensive assessments help break through the complexity and see beyond the obvious indicators of ADHD to provide a highly relevant and meaningful assessment of symptoms, impairments, and common co-occurring conditions - helping to provide individuals with the most appropriate plan to navigate any specific challenges for their long-term progress. 

Multi-source evaluations

Gathering information from multiple sources close to an individual can help to better inform practitioners.

Assessments, such as the Conners 4 (for children) and CAARS 2 (for adults) aim to obtain a broad picture of the individual by collecting observational data from parents and teachers (where relevant), observers and individuals themselves. This format greatly increases the quality of the assessment by covering a wider aspect of the individual’s day-to-day life and drawing comparisons between the informants' observations.

Day-to-day practicalities

Conners assessments have been designed with the practitioner in mind and consider:

  • Your time pressures - giving the choice of a short or long form. The short forms can be used for screening larger groups of students to explore if additional assessments would be appropriate.
  • Fairness and inclusivity, including no evidence of measurement bias regarding gender, race/ethnicity, country of residence, or parental education level. Read how Conners 4 tackles fairness and inclusivity in ADHD diagnosis
  • Reliability and test validity, using the latest norms. See further details here.
