“…Some of the factors outside of the school environment that researchers have identified as influencing the grade at which English proficiency is achieved include family socioeconomic status, parental education, neighborhood factors, the experience of discrimination, reasons for immigration (voluntary versus involuntary), social-emotional factors, length of exposure to English, and acculturation or motivation/aspiration (Bialystock & Hakuta, 1994; Krashen & Brown, 2005; MacSwan & Pray, 2005; Portes & Hao, 1998; Thomas, 2004). Some of the educational factors associated with the grade at which English language is acquired include participation in early care and education programs, parental involvement in school, teacher attitudes and characteristics, the number of limited English proficient students in the school, and exposure to well-designed bilingual education programs (Fitzgerald, 1993; Klingner, 2006; Winsler et al, 1999).…”
