Studysync is one of the worst, most flawed english curriculums currently in use
It is all-around terrible. The book is okay, aside from the fact that it misses major pieces of the stories, and the multiple-choice questions are usually fundamentally flawed. The real issue is with the Studysync assessments. They have subjective questions with only one correct answer, questions that can be interpreted multiple ways, multiple correct answers for questions with only one being marked as correct, and grammatical questions with multiple correct answers (These are the most objective questions possible, and they mess these up?!) These StudySync assessments genuinely make me wonder if the author of them read the texts the test is being given based on. This curriculum is why most students hate school.
While it has been bad enough for ELA, trying to use it for ELD has proved to be worse. There are only TWO dedicated lessons per unit for designated ELD. While this may be enough support for integrated (it's not, but let's just say it is) it is an absolute disaster if your district was sold that it was an ELD curriculum. This is misleading at best, deceptive at worse. It is designed like an English support curriculum, which is in no way helpful for my students to pass the ELPAC. Honestly, if I had all the hours I have spent going down rabbit holes trying to find things on this maze of a platform, I would be able to add a whole week to this year.
