In my school. We stopped streaming the students. Its close to the ond of the school term, so the students are asked to stay in their own respective classes during English period so as to allow their default teacher to complete the PBS assessment. Even I don't actually follow the assessment in order of each Band due to the reasons tou mentioned. Say if I've completed one assessment for Band 3, there will be several students missing out onthe assessment due to MC, absence, etc. moving on to BNd 4 assessment, I will still conduct the assessment on all students inclusing those who haven't finish out their Band 3 assessment. Why? Because its a waste of lesson period if I were to try and finish up all the student's assessment before moving on to the next level. Having 1 teacher to manage 40 students (yes, I have 40 students in my class) and trying to conduct several PBS assessment in 2/3 periods is impossible. Its possible if you're willing to close one eye and just ask the students to plagliarize other students work or simply copy the answers from the board.

PBS isn't exactly new. Its been done before. It failed the first year because of so much materials needed to be printed and photosated (incurring high cost to school and/or teacher) and spoonfeeding the students with answers. I'm not saying its a bad concept, but the implementation is very poor and 80% of the teachers have no clue to how to properly assess the class.

Supposeably, the PBS was meant so that good students will make an exta effort to raise their proficiency while helping the weaker students. But as it turns out, its the teachers who are more concern of the students and having to chase those lazy students into completing their tasks. Already i have one studens who never pass Band 2 because of frequent absence in class. It will be me who will have to asnwer to the school as to why I allow my students score poorly in PBS.
