Assessment Types Explained
Referrers often do not know which assessment to instruct. The three below are the most commonly requested.
Functional Capacity Evaluation (FCE)
A structured, standardised evaluation of a person’s physical and cognitive capacity to perform work and daily tasks. An FCE draws on interview, observation, standardised testing and, where relevant, functional task performance, and reports on current capacity, restrictions and prognosis for work.
Assessment of Daily Living Skills (ADL)
An assessment of how a person manages personal care, domestic tasks, community access, transport and other everyday activities, and what assistance they require. ADL assessments are commonly used to quantify past and future care and support needs in personal injury matters.
Expert Opinion Report
An independent opinion addressing the specific questions raised in your letter of instruction, supported by clinical reasoning and the assessment evidence. Where required, reports are prepared in accordance with the expert evidence rules applicable to the jurisdiction, and a supplementary report can be provided in response to material served by another party.
Phase One Therapy also provides Functional Capacity Assessments (FCA) for NDIS and disability support purposes. See our functional capacity assessments page for more information.

How to instruct us

1. Letter of instruction
Send your letter of instruction to Allied Health Experts requesting for Kristyn, setting out the questions you need answered, together with the relevant material: medical records, imaging, prior expert reports, statements and any surveillance material you intend to rely on. Allied Health Experts will confirm capacity, fees and an estimated turnaround of the report..
2. Conflict and capacity check
Kristyn conducts the assessment in the person’s home, in the community, in the clinic or by telehealth where appropriate. It draws on clinical interview, observation of functional task performance and standardised assessment tools selected for the referral questions. As an independent expert, Kristyn does not provide treatment, does not implement interventions with the person being assessed, and does not discuss her findings or opinion with the person ahead of the instructing party. Assessment in the person’s own environment usually produces a more accurate picture of daily function than a clinic-based appointment.
