    I am so thrilled with my purchase of the Woodcock-Johnson IV. Up to now, I was only able to screen for Dyslexia; now, I can confidently and competently assess Reading, Writing, Spelling & Maths for people 4yrs -Adults. It is so good to work with, both during testing and afterwards, when scoring the work. The scoring is easy, and the computer does the calculations. This saves time and, more importantly, the human error side of scoring other tests. I love the variety of reports that can be compiled, and I especially like the printable sheet “Profile report”, with all of the scores given on one page, almost in pictorial form. This makes structuring the written report and being able to “see the whole picture” easy for the test user (me). It also makes it easier to show people where all the scores are about each other at a glance. I am thrilled with its performance, and I’m looking forward to allowing it to help me to help so many more people with difficulties in the future. Thank you so much, Rebecca, for training me in my CCET and for doing the work on this test to make it available to me and the many more me’s (i.e. CCET trained people) to come.

    I am always adding to my resources, keeping up my CPD, and looking for improved working methods. I find time is the most significant factor. There's never enough of it, especially in the world of assessment. I inadvertently stumbled across the WJ Test of Achievement through a CPD session and I have to say, I'm so glad I did! It's a fantastic test battery that saves time, money, and effort and provides reliable results! The tests are so wide-ranging, measuring several different skills and areas it is rare to see so much offered within one test kit! They are also quick to administer, ideal for students who struggle with concentration or feel intimidated by more extended tests. The beauty of this is also it's scoring; it's so easy! No big manuals to wade through, no number crunching and no formulas to calculate either! It reduces clerical error, is practical, and is easy to use once you've familiarised yourself with or accessed the WJ IV Ach online training. I love this and recommend it to any assessors needing an alternative test kit! Best investment I've made in years! I find it so practical; I don't think I can live without this in my test toolbox now! p.s. ordering is easy too, and the staff are knowledgeable and beyond helpful!

    I started using the WJ4 early this year, and after a little teething time (mainly due to my techie skills – or lack thereof), I’ve nailed it! I love it; delighted to have a test with phonological awareness (Word Attack) and the usual range. Rebecca and co-in Education Elephant have been accommodating too. Full marks all around!
