The ATDH (Admissions Test for Dental Hygiene) exam is a comprehensive assessment that evaluates the knowledge and skills of individuals aspiring to become dental hygienists. It consists of six sections, each focusing on a specific area of study. Let’s take a closer look at what each section entails.
1. Reading Comprehension:
This section assesses the candidate’s ability to understand and interpret written passages. It may include excerpts from scientific articles, dental hygiene textbooks, or patient case studies. Candidates are required to answer multiple-choice questions based on the given information.
2. Language Usage:
The Language Usage section evaluates the candidate’s understanding of grammar, vocabulary, and writing skills. It may include questions on sentence structure, word choice, punctuation, and other aspects of written communication. Candidates are typically asked to choose the correct grammar usage, identify errors in sentences, or complete sentences with appropriate words or phrases.
3. Quantitative Reasoning:
The Quantitative Reasoning section measures the candidate’s problem-solving skills and numerical proficiency. Questions in this section often involve calculations, data analysis, and interpretation of graphs or charts. Candidates may be asked to solve mathematical problems, apply basic algebraic concepts, or make quantitative comparisons.
4. Perceptual Ability:
This section assesses the candidate’s spatial visualization and perceptual skills, which are crucial for dental hygienists. Candidates are presented with visual stimuli, such as two- or three-dimensional figures, dental models, or radiographs, and are required to answer questions based on their interpretation of the visual information. The questions may involve pattern recognition, spatial reasoning, or the ability to manipulate objects mentally.
5. Biology:
The Biology section focuses on the candidate’s knowledge of biological concepts and processes relevant to dental hygiene. Questions may cover topics such as anatomy, physiology, microbiology, and basic genetics. Candidates may be asked to identify anatomical structures, understand physiological processes, or demonstrate an understanding of microbiological principles.
6. General Chemistry:
The General Chemistry section evaluates the candidate’s understanding of basic chemical principles and their application in dental hygiene. Questions may cover topics such as atomic structure, chemical bonding, solution chemistry, or acid-base reactions. Candidates may be asked to solve chemical equations, balance chemical reactions, or calculate concentrations.
The ATDH exam aims to assess a wide range of skills and knowledge necessary for success in the field of dental hygiene. It covers areas such as reading comprehension, language usage, quantitative reasoning, perceptual ability, biology, and general chemistry. Aspirants should prepare thoroughly in each of these areas to perform well on the exam.
