Attentional Performance and ADHD Diagnostic Testing

Attention is a vital component of the learning process, and different types of attentional difficulties have different implications for learning and intervention strategies. 


Executive Function skills are the mental processes that enable us to plan, focus attention, remember instructions, and juggle multiple tasks successfully.


Our clinicians select from a range of available tests to provide a comprehensive evaluation of different aspects of attentional and executive functioning:

  • Test of Everyday Attention for Children (TEA-Ch)

    The TEA-Ch measures children’s abilities to:

    • Switch their attention from one task to another
    • Withhold (inhibit) verbal and motor responses
    • Sustain their attention
    • Selectively attend
    • Divide attention between two tasks

    The subtests are sensitive to the developmental progression of attentional skills and allow analysis of the child’s progress in this important area of development.


    Age range: Junior (5-7 years) and adolescent (8-15 years) version

  • Test of Everyday Attention for Adults (TEA)

    The TEA gives a broad based measure of three important clinical and theoretical aspects of attention:

    • Selective attention
    • Sustained attention
    • Attentional switching 

    Age range: 18 to 80 years

  • Developmental NEuroPSYchological Assessment (NEPSY)

    The NEPSY assesses a range of cognitive abilities including:

    • Executive functioning
    • Attention
    • Language
    • Memory and learning
    • Sensorimotor functioning
    • Social perception
    • Visuospatial processing

    The results provide information relating to typical childhood disorders, which can lead to accurate diagnosis and intervention planning for success in school and at home.


    Age range: 3 to 16 years

  • Delis-Kaplan Executive Function System (D-KEFS)

    The D-KEFS assesses key components of executive function including:

    • Problem solving
    • Verbal and spatial concept formation
    • Flexibility of thinking
    • Fluent productivity in the verbal and spatial domain
    • Verbal inhibition
    • Planning and reasoning
    • Impulsivity
    • Hypothesis testing
    • Verbal and spatial abstract thinking
    • Deductive reasoning
    • Metaphorical thinking and comprehending abstract thought

    Age range: 8 years onwards

  • Comprehensive Executive Function Inventory (CEFI)

    The CEFI evaluate executive function strengths and weaknesses in the following domains:

    • Attention 
    • Emotion regulation
    • Flexibility 
    • Inhibitory control 
    • Initiation 
    • Organisation 
    • Planning
    • Self monitoring 
    • Working memory 

    Age range: 5 to 18 years old, Adult version 18+

  • MOXO computerised continuous performance test (d-CPT)

    The MOXO d-CPT provides measurements of all four core symptoms of ADHD:

    • Hyper-Reactivity
    • Inattention
    • Timing
    • Impulsivity

    Age range: Child (6 to 12 years) and Teens/Adult (13 to 70 years) versions

  • Conners Questionnaire

    The Conners questionnaire assesses ADHD symptoms as well as its most common comorbid problems and disorders:

    • Inattention
    • Hyperactivity / Impulsivity
    • Learning Problems
    • Executive Functioning (Parent & Teacher)
    • Defiance / Aggression
    • Peer / Family Relations

    It is a multi-informant assessment that takes into account home, social and school settings, with rating forms for parents, teachers and youth.


    Age range: 6 to 18 years

  • Wender Utah Rating Scale

    The Wender Utah Rating Scale is a self-report instrument that is designed to retrospectively evaluate the presence and severity of childhood symptoms of ADHD in adults.


    Age range: 18+ years
