I'm glad you're considering using Khan Academy to help instruct your students! In terms of using it for your classes, have you tried making classes within the site and assigning tasks to your added students? The Class system on Khan Academy has been heftily developed for that purpose, and if you haven't encountered it yet, I would really recommend it for your teaching needs.

If you have tried using the Class and Teacher Dashboard system, but would still like some sort of developed product to use in your school, please let me know and I can escalate your request. 

I have not used Khan Academy in my classroom because every week we are required to have each student work on iReady for 45 minutes with only 6 computers so I do not have the time to devote to using an additional product. Our school purchases iReady and monitors its use. Each year they ask for suggestions of alternatives, but I don’t know of any. All I know is I don’t care for iReady and neither do most of my Kindergarteners!

I understand your concerns with the iReady program; I've heard a lot of complaints about it on other platforms. If it's frustrating, do you think you might be able to propose using the Khan Academy classes option as a substitute to that program, and prevent your school from having to pay for a program that your students don't like? I'd really recommend suggesting Khan Academy as a free alternative to iReady; please do consider talking to your school about using it. 

Other than that, if you would recommend that Khan Academy have a separate, customized package specifically for use in schools, I can escalate that feedback to higher members of KA. 

Yes, that is what I am recommending. The free Khan Academy for the classroom is not quite what my school is looking for. We want something that has chronological lessons, practice, and assessments that we can use to gather data. We use iReady data (tells if child is performing below, on, or above grade level) as a fairly accurate predictor of how students will perform on standardized tests.

My daughter uses the Khan Academy Kids app which is very motivating for young children, but she is 6 now and getting a little too old for it. I’m suggesting that KA design something similar to iReady, focused on math in the primary grades PreK-5, and engaging for children just like the app designed for 4-6 year children.

I think I see what you mean; the Khan Academy Classes system does have a series of courses, video lessons and articles, as well as assessments, but does not report on data about the child's predicted performance. I'll go ahead and escalate your idea further so that such a system specifically for school-wide use can become a possibility. 

Thanks for the great feedback! I'll try to encourage its implementation.
