The K12 curriculum demands a wide variety of both direct and higher-order thinking skills questions with varying question formats across all subjects and grades. It is difficult to find a team of experts who are equipped with subject-matter knowledge as well as an understanding of common core standards and other classification frameworks for learning objectives. Even some highly knowledgeable subject experts are not equipped with the writing skills required for developing assessments across all grades. Also, for clients based in different time zones, maintaining delivery and a meeting schedule can be a hassle.
