May an LEA use different textbooks or instructional materials from the same adoption in different classrooms teaching the same course?
Yes. LEAs must use textbooks or instructional materials from the same adoption for an entire grade level or course, but these instructional materials may be from different publishers; for example, two teachers within an LEA may choose to use algebra 1 textbooks from different publishers, as long as both books are from the same adoption list. Please reference EC Section 1240.3 above.
