Assessment of Motor and Process Skills

The Assessment of Motor and Process Skills (AMPS) is an innovative observational assessment that is used to measure how well a client performs familiar activities of daily living (ADL). The quality of occupational performance is evaluated by rating the effort, efficiency, safety and independence of 16 motor skills and 20 process skills, while the person is doing chosen, familiar and life relevant ADL tasks. There are over 125 ADL tasks included in the AMPS, from very easy self-care tasks to multi-step domestic tasks (including outdoor tasks and shopping).
​​5-day training workshop

This provides occupational therapists and occupational therapy students, critical information related to the theoretical basis of the AMPS as well as experiential learning of administering and scoring the AMPS. Participants obtain valuable hands on information regarding occupation based assessment and interventions as well as viewing and scoring recorded and live AMPS observations during the course.

Rater calibration

Rater Calibration is required following the 5 day course, potential AMPS raters must complete 10 live observations after the course and submit these data for analysis. Rater calibration allows each rater’s severity to be determined along with ascertaining if the rater is scoring the AMPS in a reliable manner.

The AMPS provides a tool that:

  1. Supports occupation centred practice, as it requires the ADL tasks that the person performs for the assessment to be chosen by the person, meaningful and relevant to his or her daily and living situation.
  2. Gives occupational therapists with a powerful and sensitive tool that an assist with intervention planning and measure outcomes — providing evidence that a client’s occupational performance has changed.
  3. Generates ADL measures that can be collaboratively with clients to plan occupation-based and occupation-focused intervention, develop occupation-focused goals, and write occupation-focused documentation.
  4. Requires no special equipment and can be administered in any relevant setting within 30-40 minutes
  5. Uses a measurement model that allows a therapist to determine the ADL ability of the person, while taking into account the relative challenge of each ADL task the person performed. As a result, people who perform different ADL tasks can be directly compared.
  6. Uses the measurement model to analyse a person’s scores and generate ADL motor and process ability measures, which are adjusted, to account for the severity of the rater who scored the person’s performance. As a result, a person’s ADL ability measures are not biased by the rater who observed the performance.
  7. Is designed to be administered to children over the age of 2 years, adolescents, adults and older adults for whom there is concern about ADL task performance. The diagnosis of the person or the reason for their functional limitations therefore does not matter.
  8. Has been standardised internationally and cross-culturally on more than 100,000 subjects.

The limitations of the AMPS:

  1. Participation in the 5-day training course and successful completion of the calibration process is required to use the AMPS.
  2. Rater calibration involves each potential rater completing 10 AMPS assessments after the course and submitting the data for analysis, within 3 months, to demonstrate they are scoring in a valid and reliable manner.
  3. The AMPS computer-scoring software is only available to persons who successfully complete the AMPS training and calibration process.
  4. The AMPS is not suitable for the assessment of children under the age of 2 years or persons who do not need or who are unwilling to participate in simple daily life tasks.
