Either test is acceptable testing for Lville. Bear in mind however the math on the ISEE is harder(from what my child said) and the LA is harder on the SSAT (again from what he said). Also there is one SSAT that is easier than them all but it changes from year to year. MY kid took Sep, Oct and Jan and he said Jan was easiest. That might be because he already was accustomed to taking the exam. He also said the location of testing made i dif for him. The stark white walls at one testing place vs the lovely windows at the Lville testing place…who knows…but he got in. Good luck. You are starting early so u will be fine.
