The first administration of the Stanford 10 was conducted in the spring of 2004. It was employed using the same methodology used to administer the Stanford 9 from the spring of 1999 to the spring of 2003. It should be noted that in 2009, Pearson, Inc. updated the Stanford 10 to the 2007 norms. The previous Stanford 10 results used 2002 norms. This update caused a shift in the NPR and NCE scores, which is typical when a test changes norms. The Stanford 10 was designed to assess student achievement in reading, mathematics, language, environment/science, social science, spelling, study skills, thinking skills and listening and was developed in an effort to update the previous edition that was published in 1996. Specifically, it was constructed to 1) update content to align with current educational and curriculum trends; 2) update the normative information to make score interpretations and performance generalizations more valid; 3) increase and improve the kinds of information available from assessment and; 4) revise the appearance of the test items to make them more relevant to students.
Aprenda: La Prueba De Logros En Español Segunda Edición (Student Achievement): The Aprenda is a norm-referenced achievement test that measures HISD Spanish-speaking students’ academic performance when compared to the performance of Spanish-speaking students from a nationally representative sample. Spanish-language measures of academic achievement are designed to assess the level of learning attained by English Language Learners (ELLs) and it is HISD policy that all ELL students in grades 1–8 who receive reading and language arts instruction in Spanish take the Aprenda.
The Aprenda 2 was first administered in 1997, using 1996 norms, and continued to be administered through 2002 when the original Aprenda (first edition) rplaced the Aprenda 2, using the updated 2001 norms. In the spring of 2005, HISD began employing the newly developed Aprenda 3 based on the 2004 norms.
Although parallel in content to the Stanford 10, the Aprenda 3 is not a translation. Subtests in the following academic areas were included in the Aprenda in order to provide a complete assessment of educational achievement – reading, language, mathematics, listening, science and social science. For all subtests, expect Calculos Matematicos (Mathematics Computation), test items were developed entirely in Spanish in order to ensure a non-biased test construction process. The Calculos Matematicos subtest, which contains only numerals, was taken directly from the Stanford Achievement Test Series in order to provide a statistical link between the two batteries.
