INSTRUCTIONS FOR COMPLETION OF SCOPE/METHOD ASSESSMENT REVIEW
Please complete table for each parameter/test/technology and the corresponding method(s) in the following categories:

Parameter, Test Name or Technology: For calibration labs, list parameter and tool (dimensional-calipers, force, etc.); For testing labs list Test category and name (Chemical, Biological, etc.) and GC-MS or Salmonella

Depth of Assessment: Record the extent to which the parameter/test was assessed as follows:
o
O = Observed Calibration or Test
o
I = Interviewed Person(nel)
o
P = Procedure Reviewed
o
E = Equipment Inspected
o
F = Field (On-Site) Calibration and/or Test
You may have a combination of the above (e.g. O/I/P, I/P, I/E, O/I/E/F) You must verify, at a minimum, that the laboratory has the equipment, method, and trained personnel to perform each calibration/test
on the proposed Scope of Accreditation.

Personnel Interviewed: List name(s) of personnel with prospective competence for the method.

Environmental Conditions,: Indicate whether the environment/facility/equipment was suitable for the methods listed, and any environmental monitoring devices (which may also require traceability)..

Standards/Equipment//Reference Materials: all reference standards and equipment utilized, trying to list all those mentioned on the proposed scope of accreditation,

Procedure/Operating Instructions: Indicate the specific laboratory internal procedures or instructions for performing the calibration or test, and whether they were acceptable. Be sure to note the same methods as noted on the
proposed scope of accreditation.

Measurement Uncertainty: Indicate whether uncertainty analysis is required for the method; if required, indicate if laboratory analysis is acceptable. May indicate to be verified later (TBV)

Verification/Calibration: Indicate whether the calibration or verification data for the relevant equipment is acceptable, and any objective evidence observed.

Sampling; Handling/Preparation of Items: Indicate all protective gear used for the methods, whether the laboratory performs any sampling for the listed methods, and indicate if those activities, as well as any handling or
preparation performed, are acceptable.


Quality Checks: Indicate what quality checks are in place and whether they are acceptable.
Records: Indicate whether the appropriate records are maintained for the listed methods, and what records were reviewed. Note all hand-written. Logbooks, or forms utilized. Many may have differing record retention times.

Report/Certificate: Indicate whether the results for the listed methods are appropriately reported in accordance with 17025 and any requirements of the methods. Note if reports issue out of a database, electronic or templates.
