Why did NashTech's new hires in Vietnam need stronger spoken English?

NashTech wanted newly onboarded engineering graduates to communicate confidently with international clients from the start of their careers.

The challenge was building consistent English practice habits fast, inside a short onboarding window, without disrupting an already packed technical training schedule.

How did NashTech roll out ELSA Business for its Rookies?

Every Rookie followed a personalised ELSA Learning Path, with AI Chat roleplays and Speech Analyzer pronunciation feedback from week one.

A programme-wide Streak Contest ran in three bi-weekly rounds. It was judged on completed roleplay conversations, with ELSA gifts and shopping vouchers as prizes.

Progress was tracked with the ELSA Proficiency Score (EPS), which measures English proficiency based on speaking performance across pronunciation, intonation, fluency, grammar and vocabulary.

Did NashTech's employees actually use ELSA?

Yes. All 57 learners practised on ELSA, and learners averaged 130 minutes of study a week against a 100-minute target.

  • Weekly study time: 130 minutes on average, 130% of the 100-minute target.
  • AI Chat: 6 sessions a week on average, against a target of 2.
  • Daily practice: about 36 minutes per active day.

How was NashTech's English progress measured, and what changed?

Average EPS rose by 6 points, from 69 to 75, in 58 days, and 89% of learners improved their English proficiency.
