Case Study: Leading IT service provider upgrades L&D and completes 15,000+ communication assessments with Mercer Mettl

Leading IT Service Provider - Customer Case Study

Leading IT Service Provider is an automation-led, next-generation IT services company with 42 global offices, ~19,407 employees and USD793M in revenue. Facing widespread gaps in English proficiency, client-facing and internal communication, and lacking a tool to pinpoint training needs, the customer partnered with Mercer Mettl to improve communication skills across its workforce using SpeechX and the Writing Simulator.

Mercer Mettl combined its SpeechX communication test (with CEFR validation, proctoring and AI-powered scoring) and the Writing Simulator (automated grammar, spelling and punctuation evaluation), added customizations like human-voiced audio and tailored cut-offs, and delivered actionable reports for targeted training. The solution enabled mass assessment and remediation, drove mandated retests for appraisals and hiring, and has supported over 15,000 assessments to date, measurably strengthening the company’s L&D processes and communication outcomes.
