__________ is the standard for describing various levels of thinking skills.

Bloom's Taxonomy is widely recognized as the standard framework for categorizing different levels of thinking skills. Developed by Benjamin Bloom and his collaborators in the 1950s, this taxonomy is organized into a hierarchy that includes cognitive processes ranging from basic knowledge and comprehension to more complex skills such as analysis, synthesis, and evaluation.

This framework is instrumental in education as it helps educators design curriculum that promotes higher-order thinking and assesses students' abilities beyond mere memorization. By applying Bloom's Taxonomy, teachers can create learning objectives that encourage students to engage critically with material and apply their understanding in practical ways. The organized structure of the taxonomy allows for clear communication about learning goals and provides a basis for instructional strategies that aim to foster a deeper understanding of content.

In contexts where other influential theories, such as Gardner’s Theory of Multiple Intelligences or Piaget's Stages of Cognitive Development, may be relevant, they focus on different aspects of learning and intelligence rather than establishing a direct hierarchy of thinking skills.
