Ana and Jorge [Sibling Edition]
P. immigrated with his family 4.5 years ago, in the middle of the seventh grade. He spent a year in our school's newcomer center -- the second half of seventh and the first half of eighth -- before entering my High Point B class. He flourished, and his newcomer teacher later fielded complaints from his 10th grade English teacher that he was "very low," with the lexile score of a ninth grader.
Buried lede: P.'s sister is my class this year, in High Point B.
It took P. one year of newcomer work and background literacy (albeit poor) in his L1 to make it to HP B. It took his sister four and a half years of Open Court Reading and 45 minutes of ELD to reach the same academic performance level.
+ newcomer center
= 1 year to reach third grade performance levels
+ pull-out ELD
= 4.5 years to reach third grade performance levels
Yup. Design your instructional program accordingly.
