At Sardis Enrichment School, once-a-week clusters let groups of students choose an area of interest outside the regular curriculum and research it with like-minded students, said Gifted and Enrichment teacher Deanna Fawcett. “Tonight celebrates all of the learning of the past eight to 10 weeks,” Fawcett said. Thirty-nine age-specific clusters of kindergarten and elementary students studied topics of their choosing.
