They typically receive bilingual education or English-as-a-second-language (ESL) instructional services. In Michigan, enrollment data for limited English proficient (LEP) students is available only for those districts that operate a federal or state bilingual education program. Moreover, the number of LEP students represents both bilingual and LEP, as Michigan data does not distinguish between the two classifications for reporting purposes.

Definition:
The point in a distribution of household incomes at which half of the incomes are below that amount, and half are above it, or the average of the two middle incomes if there is no one middle income. Household income encompasses all persons 15 years or older in the household, regardless if the individuals are related to one another. Income includes wages and salaries, self-employment, interest, rentals and dividends, social security, public assistance, retirement, and disability. Since many households consist of only one person, average household income is usually less than average family income.
