Renaissance recommends testing ELL students using both the English and Spanish versions of Star Math to alleviate the language barrier these students experience. By providing test questions in Spanish you get a clearer idea of what students know, since ELL students have often mastered more than English-only tests will show.
Two students are walking along the path that leads to college and career readiness. One student is a native speaker of English. The other student is a native speaker of Spanish who has some knowledge of English. Star Spanish assessments aim to help you understand the progress both students have made towards success, and how much of the journey remains.
When the English-speaking student and the Spanish-speaking student take a Star assessment in English, each student's domain scores indicate the student's EPC or mastery of a grade-appropriate criterion-referenced assessment administered in English for that domain. Each domain score is an indicator of the student's progress toward college and career readiness in the US in an English-speaking environment. The students are walking the same path. The Spanish-speaking student's place on the path may be influenced by the student's knowledge and use of English.
While the score for the Spanish-speaking student is an indicator of the student's progress toward college and career readiness in the US in an English-speaking environment, it may not be an indicator of the student's degree of mastery of the skills in the domain. The student's ability to demonstrate mastery may be hindered by gaps in the student's knowledge and use of English. Star Spanish is designed to measure mastery of the same set of skills as Star in English, without the language hindrance.
When a Spanish-speaking student takes a Star assessment in Spanish, the student's domain scores indicate the student’s EPC or mastery of a grade appropriate criterion-referenced assessment administered in Spanish for the domains. Each domain score is an indicator of the mastery of the domain when the items used to assess that domain are presented to the student in Spanish. These domain scores, while valid for the domain, are not necessarily indicators of a student's progress toward college and career readiness in the US in an English-speaking environment.
How then are they useful? The domain scores from a Star assessment administered in Spanish are valid and reliable measures of the student's degree of mastery of the skills in a domain in cases where the items are presented in Spanish. If a domain score from an assessment administered in Spanish indicates a high degree of mastery for a domain, but the student is not at a grade-appropriate place on the college and career readiness path in an English-speaking environment, the reason may relate to the student's knowledge and use of English.
When you look at a student’s results on two tests (Star in English and Star in Spanish), you can see two different things. The Star English mastery tells you about a student's progress on the English-speaking CCR journey. The Star Spanish mastery tells you about a student's progress towards skills mastery as demonstrated in a Spanish assessment. Just as you might think about being halfway on a trip around the world as "50% done," and halfway on a trip to the grocery store as "50% done," the percent of mastery is a way of normalizing your student's pace of progress, but in no way implies that the mastery journey in English and Spanish are the same.
