All preservice teachers must take the Praxis Subject Assessments as part of teacher licensing and certification in their state. Luckily, state approved teacher education program curricula helps to prepare students to pass these exams. And, many organizations, including ETS Praxis, have created some great test prep resources to help teacher candidates hone their knowledge and skills. My favorite site is Study.com which provides diagnostic assessments and an intervention plan…targeting what you need to study.
