English Language Development (ELD) Teachers and ESL Teachers both focus on helping non-native speakers improve their English skills. While their credentials and work environments are similar, ELD Teachers often work within K-12 public schools focusing on academic language development, whereas ESL Teachers may work in private language schools or adult education settings. Both roles require similar certifications and serve overlapping populations, but their specific contexts and target audiences can differ.
