If you are working towards your degree or certificate in Educational Leadership and need to take the SLLA 6990, I recommend Kathleen Jasper's book. I bought this book after my first semester in my program and took the test halfway through my second semester. I read through this book and did the practice test twice. I also listened to her webinars which she offers for FREE and her many Youtube videos that are posted for FREE . She does have more paid options available on her website but I found the book and her free videos where more than enough. For the essay questions, I also used AI to prepare. I'll share how I used AI to provide feedback and improve my essays as I prepared for the test.
