This version of "Retention. PEPNet Tipsheet," written in Spanish, focuses on understanding the factors that research indicates are important for persistence to graduation and suggests some approaches to reducing attrition among students who are deaf/hard of hearing attending postsecondary institutions. Students who are deaf or hard of hearing and beginning their college years sometimes encounter challenges that, lacking special support, may result in their dropping out of school without any form of certification. Estimates for these students show that between two-thirds and three-quarters of those who begin their studies never graduate. From the individual's perspective, the economic benefit of receiving certification is considerable. Persons who are deaf/hard of hearing with postsecondary certification report earnings that are more equivalent to those of their hearing peers and significantly higher than their peers without a degree. Also, students who are deaf who leave college without any form of certification report earnings that are no higher than individuals who never attended college. With competition for students critical to the success of a college, administrators must learn why students decide to withdraw from college so that strategies for intervention can be identified.
