We evaluate interpreter expertise and experience together with provider capabilities, operational standards, and quality management systems to define interpretation quality and Tier levels. This provides clear selection criteria for interpreters and professional providers based on project objectives and complexity.
The AI · QMS Tier Matching System combines AI-based project analysis with QMS evaluation criteria to assess subject-matter requirements, project complexity, and each interpreter’s expertise, experience, and proficiency. By classifying project requirements and interpreter capabilities by Tier, the system enables appropriate interpreter selection and assignment while minimizing variation in interpretation quality.
※ Tier classifications are not official industry ratings and may vary by company. They are provided for reference only to help evaluate interpreter expertise, provider capabilities, and quality management standards.
(Interpreter → Select and assign interpreters at the appropriate Tier based on project complexity, maintaining quality whilereducing interpretation costs)

※ Interpreter Tiers are determined through a comprehensive assessment of expertise, professional proficiency, relevant project experience, and the ability to handle complex assignments—not simply by years of experience or interpretation rates. Selecting and assigning interpreters at the appropriate Tier based on each project’s objectives and complexity is key to minimizing variation in interpretation quality.


Interpretation and translation providers are classified into Tiers based on a comprehensive assessment of their professional staffing capabilities, project management standards, Quality Management System (QMS), confidentiality and information security practices, and ability to handle complex projects. This framework provides criteria for selecting the professional provider best suited to each project’s requirements.

It does not refer to differences in the language proficiency or interpreting skills of individual interpreters, but rather to differences in the provider’s project management capabilities and quality management system.
※ Tier classifications and price ranges do not represent official industry ratings or standardized pricing and may vary depending on each provider’s internal operating criteria and project requirements.
