Follow these Best Practices when planning models and reference points (see publication or Manual):

Scores are calculated for each region within an assessment area. Jurisdictional boundaries are often appropriate.

Select from Ten commonly assessed goals

See Conceptual and Practical guidance for each goal

• Understand each goal, maintain the definition but think critically how to represent it (Best Practices 1 & 3)
• Work on similar goals simultaneously
• Evaluate reference point, pressures, resilience while collecting data

Prepare data and models for the Toolbox (Appendix 2 & 3)

Information (data and/or indicators) are required to calculate Goal status, Pressures, and Resilience

Gather open-access data that will be updated regularly

Data must be at appropriate spatial and temporal scales

Give preference to high quality data collected by respected organizations

If can't find ideal data, use proxy data or gapfill

Once you have:

• gathered data
• developed goal models with available data
• finalized spatial boundaries with available data

Request a Toolbox Tailored Assessment Repository

• where your data will be stored, formatted, and managed
• scores will be calculated using the Toolbox Core package
• use of R and GitHub are required

Format, store, and register data

Script preparation process as much as possible for transparency, explanation, and comparable future assessments

Toolbox requires specific preparation:

• each data layer as a separate .csv file
• each layer has long formatting
• most layers rescaled to 0-1
• each layer must be registered
