Starting a new assessment will clear all current answers.

1
Provide the assessment information Provide the assessment information, including the evaluated ubiquitous computing environment, evaluator's name, and assessment date.
2
Choose how you want to perform the assessment Choose the format that best fits your workflow.
  • Web Version — interactive assessment with automatic progress tracking, automatic assessment summary, report generation, and the ability to save and resume your progress using backup (.json) files.
  • Printable PDF — print-ready version for offline or paper-based assessments completed manually, with a Notes/Observations field for each recommendation.
  • Blank Spreadsheet (.xls) — spreadsheet version for manual completion, documentation, filtering, and later analysis.
If you use the Web Version, remember to save your progress regularly using Save Progress (.json). Whenever you want to continue an existing assessment, simply use Resume Assessment (.json).
3
Assess each recommendation Assess each recommendation according to the evaluated ubiquitous computing environment.
Choose:
  • Yes (Supports Equitable Access) when the evaluated environment supports the recommendation;
  • No (Improvements Required) when the recommendation is not fully addressed. Use the notes/observations field to describe what should be improved;
  • Not Applicable (N/A) when the recommendation does not apply to the evaluated context. A Not Applicable (N/A) assessment does not indicate a limitation of either the evaluated environment or the UbiAccess+ instrument; it simply indicates that the recommendation is not relevant to that particular scenario.
Use the optional notes/observations field to record evidence, observations, or rationale that may support future improvements.
4
Review the Assessment Summary The Web Version automatically generates the Assessment Summary as recommendations are completed.
The Printable PDF and Blank Spreadsheet include spaces for manually summarizing the assessment after completion.
5
Export Assessment Results After completing the assessment in the Web Version, export the results in the format that best fits your needs.
6
Consolidate Multiple Assessments (Web Version only) If the same ubiquitous computing environment is assessed by multiple evaluators, the Web Version can consolidate their saved backup (.json) files into a single report. Each recommendation is compared across all completed assessments to identify consensus, divergent assessments, and incomplete assessments when applicable. The consolidated report groups recommendations by their assessment outcome (Yes, No, or Not Applicable), preserves the evaluators' supporting observations, and highlights recommendations that may require further discussion or review.

The 44 recommendations are distributed across the 6 areas below. Each recommendation's ID starts with its area's two-letter code, followed by a sequential number — e.g. Digital (DI) has recommendations DI01–DI02, Environment (EN) has EN01–EN13.

Assessing UbiAccess+ Recommendations

Assess each recommendation according to the evaluated environment. Select Yes (Supports Equitable Access) when the evaluated environment supports the recommendation, No (Improvements Required) when improvements are required, or Not Applicable (N/A) when the recommendation does not apply to the evaluated context. Use the optional notes/observations field to record evidence, observations, or rationale that may support future improvements and facilitate the interpretation of the assessment results. Each recommendation is identified by a two-letter area code followed by a sequential number (e.g., DI01, EN05, SP03). See the Assessment Guide above for additional guidance.

Assessment Summary

Recommendations are automatically grouped according to their assessment outcome (Yes, No, or Not Applicable) as the assessment progresses.

ASSESSMENT SUMMARY

Improvement Opportunities (NO Conformance)

Recommendations marked NO identify opportunities for improving equitable access. Notes document evidence, justify the assessment, and may support future improvements.

Recommendations Supporting Equitable Access (YES Conformance)

Recommendations marked YES indicate aspects of the scenario that already support equitable access and should be maintained.

Not Applicable in This Scenario (N/A)

Not Applicable (N/A) recommendations do not indicate a limitation of either the assessed environment or the UbiAccess+ instrument. They simply indicate that the recommendation is not relevant to the assessed scenario.

Consolidate Multiple Assessments

Load the saved backup (.json) files from different assessments of the SAME environment, and generate one consolidated report showing where they agree — and where they don't.
