This study describes the effectiveness of a read-aloud cross-age partnership in service learning among students of various age groups (pre K-college sophomore) attending the different schools located on a university campus. Research-based theories of read-aloud to children were used to train the reading volunteers. Multicultural story books aided the participants towards embracing cultural diversity and understanding on campus. Following two pre-program questions, all adult readers received training and reading guides related to read-aloud techniques, style, and poise. A post-reading analysis included focus group classroom-teacher dialogues; a twelve-item reader survey; and field observations of reading attributes. The results of the read-aloud showed tangible and noteworthy benefits to readers and children. Read-aloud promoted growth in textual comprehension by the children as well as critical thinking skills of the readers. Cultural awareness and cross-age communication was also noticed. The enthusiasm shown by the participants has generated a continuation of this partnership.
