How Does Localization Impact Training Outcomes? A 90-Day Study

What effect does training localization have on employee learning outcomes?

To find out, Articulate ran an internal analysis of anonymized and aggregated course data to examine how learner behavior changed after employing localization. The study focused on two key metrics over a 90-day period: course completion rates and the time learners took to complete assigned courses.

Read on to explore the study methodology, statistical analysis, and data findings.

What is training localization? Definition and background

E-learning localization is the process of adapting course content for multiple languages and cultural contexts so it resonates with global learners. Research widely supports that localized employee training can improve comprehension, increase engagement, and enhance overall training effectiveness across linguistically or culturally diverse teams.

While these benefits are well documented, Articulate wanted to examine our own data to better understand how localization influences actual learner behavior.

Research methodology: how we measured the impact of localization on learning

A 90-day observational analysis

Articulate conducted an internal observational analysis based on anonymized and aggregated customer usage data. The study reflects real learner behavior in real-world conditions, not a lab environment. Here’s how we gathered the data:

• Who: The data came from 115 Articulate 360 subscriptions who use Reach with a paid localization contract. For more context:
  • Reach is Articulate’s integrated content delivery tool. It enables course creators to quickly share training with learners and track their progress—without the complexity of a traditional learning management system (LMS).
  • Localization is Articulate’s built-in translation and validation solution. Users can translate content into 80+ languages with AI, and invite human validators to check for accuracy and review live course previews before publishing.
  • Used together, these features allow teams to publish multiple language versions of a course as a single source file, eliminating the need to export, translate, and re-import course files.
• What: We looked at two primary training performance indicators:
  • Course completion rates
  • The amount of time learners spent completing courses

• How: Aggregated and anonymized learner behavior metrics were compared before and after the localization contract start date. This allowed us to observe how course completion patterns changed after localization was introduced.
  • Aggregated means the data was combined across many learners and organizations to identify overall patterns, rather than analyzing individual users. Looking at data in aggregate helps reveal more reliable trends by reducing the impact of individual outliers.
  • Anonymized means all personally identifiable information was removed, so no individual learner or organization could be identified in the data. This approach protects customer privacy and ensures that sensitive information remains secure.
• When: Results were analyzed across 30-, 60-, and 90-day windows to understand how outcomes shifted over time.

Research findings: how localization affected training performance

1. Course completion rates increased after localization

Among Articulate customers using Reach and Localization, average course completion rates increased from 77.4% to 83.4% over a 90-day period, a 6-percentage-point increase.

While individual results vary, the overall trend showed improved completion after localization was employed.

2. Learners completed localized courses faster

We also examined how long it took learners to complete courses before and after localization. Across all available data:

• The median time to complete a course decreased by approximately 50% after localization.
• Mean completion times showed an even larger drop, though these results reflect extreme outliers.

Because some courses had unusually long completion times before localization, median values provide a more accurate picture of the typical learner experience.

After localization, course completion times were more consistent and less variable, suggesting learners processed content more efficiently overall.

What does the data suggest about localization and employee training?

Higher completion rates suggest learners are more likely to finish courses when language barriers are reduced. Faster completion times suggest they can move through content more efficiently. Our hypothesis: Efficiency increases when learners no longer need to expend extra effort translating or reinterpreting information as they proceed through the course.

For workplace learning teams, that can mean:

• Less friction for global or multilingual audiences
• Faster time to proficiency for employees who need to apply skills on the job
• More consistent learning experiences across regions and roles

Benefits of training localization beyond the study

These 90-day findings show only part of localization’s broader benefits. External research reinforces how localization enables:

1. Better, faster learning. Training in a learner’s native language is easier to understand, apply, and remember.
2. Higher-quality, more consistent training. Translation addresses local needs while keeping training standardized across regions.
3. Safer, more compliant workplaces. Removing language barriers reduces miscommunications that can lead to accidents or compliance issues.
4. Stronger employee engagement. Culturally relevant, relatable training helps to increase participation and buy-in.
5. Inclusive learning cultures. Localization supports broader access to professional development opportunities—no matter where employees work.
