1. TAT Test
This test consists of 30 images and one blank card (a white image). Most of the images depict people in various situations. Participants are asked to describe these images in detail, creating vivid and elaborate stories about them. They should describe the characters, the situations, what the characters are doing, what happened to them before, and what might happen in the future. Some of the images are designed specifically for certain genders or age groups, while others are universal. This test uses a projection method, reflecting the inner thoughts and psychological conflicts of the person taking the test.

2. Rorschach Test
The Rorschach method consists of 10 inkblot images, with 5 in black-gray and 5 in multiple colors. Participants are asked to view each image in sequence and respond to the question, 'What does this resemble?' The results are then analyzed based on various indicators. This is also a projection technique used to assess psychological structure, revealing one's inner thoughts, conflicts, and perspectives on life and values.

3. Bar-On EQ Test
Bar-On developed a questionnaire to measure Emotional Intelligence (EI), believing it consists of skills, abilities, and competencies that impact one's success in managing environmental pressures. The Bar-On scale measures abilities and skills that aren't purely cognitive, dividing them into 5 key categories: 1. Recognizing, evaluating, and expressing emotions. 2. Understanding others' feelings and interacting accordingly. 3. Regulating and managing emotions. 4. Managing change, adapting, and solving personal and interpersonal issues. 5. Utilizing positive emotions and self-motivation. This questionnaire also covers areas such as self-awareness, assertiveness, self-esteem, self-expression, autonomy, empathy, interpersonal relationships, problem-solving, practicality, flexibility, stress tolerance, impulse control, happiness, and optimism.
4. MBTI Test
The MBTI test is based on the theories of Carl Jung and Isabel Briggs Myers. Jung proposed that personality consists of three core elements: orientation (introversion or extraversion), perception (intuitive or sensing), and decision-making (thinking or feeling). Myers extended this by adding a fourth factor, indicating whether an individual is more structured or flexible. Together, they identified 16 personality types and developed 72 corresponding assessments with ratings A, B, C, D, and E. Respondents answer based on their emotional tendencies, from neutral to emotional, and their raw scores are compared against a standard reference table to determine their personality type. This test is widely used in management and project settings, emphasizing individual differences. However, critics argue that the MBTI lacks scientific reliability and is overly influenced by emotional fluctuations.

5. NEO-PI-R Test
The NEO-PI-R scale is one of the most popular personality assessments in psychological practice, particularly in clinical psychology. The development of this scale began in the 1970s by Costa and McCrae. Initially, it included just three factors: extraversion, neuroticism, and openness to experience. However, by 1992, the authors expanded it to five factors, known as the Big Five or Five-Factor Model. This model posits that these five dimensions represent core aspects of personality. The NEO-PI-R scale includes five primary traits, each consisting of six facets, and each facet has eight items, totaling 240 questions. The five traits are: Neuroticism (anxiety, hostility, depression, self-consciousness, impulsivity, vulnerability), Extraversion (friendliness, sociability, assertiveness, activity level, excitement-seeking, positive emotions), Openness to Experience (imagination, aesthetic sensitivity, attentiveness, actions, ideas, values), Agreeableness (trustworthiness, straightforwardness, altruism, compliance, modesty, kindness), and Conscientiousness (competence, orderliness, responsibility, achievement striving, self-discipline, cautiousness). This tool is used to assess various personality traits and has served as the foundation for the Five-Factor Theory, which distinguishes between general personality traits and the specific characteristics of individuals.

6. Gille Intelligence Test
The Gille Intelligence Test, also known as the "Diverse Intelligence Test," was developed by R. Gille in 1944. This test is based on theories of multiple intelligence and the developmental psychology of J. Piaget. After being standardized by the National Population Committee of France on a sample of 9,500 children aged 6 to 14 years, from diverse social backgrounds (farmers, workers, small traders, and intellectuals) in 1954, it became widely used in France and other countries to measure the intelligence of children aged 6 to 12, both literate and illiterate. The test consists of 62 drawings depicting various themes and can be administered to groups. It aims to assess cognitive abilities, including comparison, classification, perception of quantity, weight, size, space, time, object recognition, logical reasoning, and the ability to abstract from concrete experiences. The results are scored and compared against a standardized reference.

7. Test trẻ em Kaufman K - ABC
Theo Kaufman, trí tuệ là năng lực xử lý thông tin, giải quyết một cách có hiệu quả các vấn đề không quen thuộc. Cũng phải nói thêm rằng Kaufman phân biệt 2 loại xử lý thông tin: xử lý theo chuỗi/ liên tiếp và xử lý đồng thời. Khi chúng ta đọc,thông tin được chủ yếu xử lý theo chuỗi. Khi chúng ta quan sát địa hình/ không gian thì thông tin được xử lý chủ yếu là đồng thời.K - ABC là một trắc nghiệm cá nhân, đo cả về trí tuệ và phong cách giải quyết vấn đề, xử lý thông tin. Trắc nghiệm dành cho trẻ từ 2, 5 tuổi đến 12, 5 tuổi. K - ABC gồm 5 thang lớn:Thanh xử lý thông tin theo chuỗiThanh xử lý thông tin đồng thờiThanh xử lý tâm thần kết hợpThanh thành tựuThanh phi ngôn từTrắc nghiệm hiện hành có 16 tiểu test, trong đó có 10 tiểu test đánh giá xử lý thông tin theo chuỗi và đồng thời; 6 tiểu test đánh giá thành tựu học tập: đọc, làm tính. Không phải tất cả tiểu test đều phủ hết độ tuổi 2,5 tuổi đến 12,5 tuổi nên có thể trẻ không phải làm hết 16 mà chỉ cần làm 13 tiểu test.10 tiểu test đánh giá xử lý thông tin gồm những item thực hành nên nhà tâm lý có thể quan sát trực tiếp và đánh giá về việc trẻ có hiểu cách làm hay không. Trong 10 tiểu test này, thì có 7 tiểu test đánh giá xử lý đồng thời còn 3 tiểu test đánh giá xử lý theo chuỗi, trong đó có 1 tiểu test là đánh giá trí nhớ ngắn hạn. Tất cả item của 3 thang tổng quát đầu ( thang đo xử lý thông tin theo chuỗi; thang đo xử lý thông tin đồng thời và thang đo xử lý thông tin kết hợp) đều cố gắng giảm thiểu ảnh hưởng của ngôn ngữ và các kỹ năng trẻ đã học được. Thang thành tựu đánh giá kiến thức trẻ học được trong nhà trường. Nhiều item của thang đo này có thể thấy được trong các trắc nghiệm thành tựu khác hoặc trong phần ngôn từ của các trắc nghiệm trí tuệ. Thang phi ngôn ngữ là một dạng rút gọn của thang đo xử lý tâm thần kết hợp. Thang đo nhằm đánh giá trí tuệ của những trẻ có rối loạn ngôn ngữ hoặc có rối loạn thính giác hoặc những đứa trẻ không nói được bằng tiếng anh. Các bài tập đều có thể thực hiện bằng cách ra hiệu, hoặc chỉ vào đáp án đúng.

8. Adult IQ Test
One of the most prominent adult IQ tests is the Wechsler Adult Intelligence Scale (WAIS). Before this test, several versions were developed, including: 1939: Wechsler Bellevue, 1946: Wechsler Bellevue II, 1955: WAIS, 1981: WAIR, 1997: WAIS III, and the most recent, 2008: WAIS IV, which is widely used worldwide. The purpose of this test is to assess general intelligence and its components. Wechsler’s view of intelligence is that it is a collection of measurable functional units. The earlier versions typically evaluated IQ with two primary areas: Verbal (including vocabulary, general knowledge, and verbal reasoning) and Performance (including tasks like picture completion, block design, digit symbol, and detail finding). The WAIS IV, the latest version, includes 10 subtests and 4 main indices: 1. Verbal Comprehension Index (language-based concept formation, verbal reasoning, and knowledge acquired from the environment), with subtests like vocabulary, similarities, and information. 2. Perceptual Reasoning Index (spatial processing and integration of visual-motor skills), with subtests like block design, matrix reasoning, and visual puzzles. 3. Working Memory Index (memory and language reasoning), with subtests like digit span and arithmetic. 4. Processing Speed Index (speed of hand-eye coordination), with subtests like coding and symbol search. The test is designed for adults over the age of 16 years and 11 months. It is considered one of the most reliable tools for measuring IQ, with scoring based on a standard distribution curve and a mean value with a set standard deviation.

9. Raven’s EQ Test
This test was introduced in 1936 by the British psychologist Raven. He believed that this method could assess cognitive abilities on a broad level. It is a non-verbal, multiple-choice test based on a 'progressive matrices' structure. The entire test consists of 60 questions, divided into five groups labeled A, B, C, D, and E, each containing 12 questions. The test's unique characteristic is that each subsequent group is harder than the previous one, with each question in a group becoming progressively more difficult. To categorize the groups, the following principles are applied: Group A assesses the completeness and continuity of patterns, requiring participants to fill in missing parts of the pattern, allowing for the evaluation of the ability to distinguish fundamental structural elements and identify their relationships. Group B involves comparing pairs of images to identify similarities. Group C examines continuous structural changes, with exercises containing changes aligned with development principles, either horizontally or vertically. Group D tests the ability to rearrange images, which also occurs along horizontal or vertical axes. Group E focuses on analyzing and breaking down whole images into parts. This is the most complex task, requiring differentiation and synthesis thinking. The Raven test is typically used for adults aged 15 to 60. There are also versions such as the Raven Colored Progressive Matrices, designed for children aged 5 to 11, and an advanced version with 60 questions, split into two groups: Group 1 with 12 questions and Group 2 with 48 questions. This advanced version is aimed at adults, including those with above-average intellectual ability. The Raven test is widely used in Vietnam and other countries due to its language-neutral nature, avoiding the complexities of translation and adaptation. It is easy to administer and score, and does not have a time limit. On average, it takes 20 to 30 minutes to complete, making it suitable for most people. However, this flexibility can be a drawback, as the test could be completed more easily with extended time.

10. The MSCEIT Test
In 2000, the Multi-factor Emotional Intelligence Scale (MEIS) was developed to measure the four components of EI, which include the recognition of emotions in faces, stories, music, and drawings; the ability to integrate emotions into perception and cognition; the understanding of emotional causes and dynamics; and the ability to manage and control emotions. This scale has high validity and reliability, although it is time-consuming and contains some sub-tests with questionable reliability and unclear scoring methods. In 2002, Mayer, Salovey, and Caruso introduced an improved version of the EI test, the MSCEIT, which focuses on four areas: Emotional Experience (factors 1 and 2: recognizing emotions and integrating them into thinking) and Emotional Strategy (factors 3 and 4: understanding emotions and managing them). These four factors are measured through 8 sub-tests, identified by numbers. Factor 1: Emotional perception includes (A, E) through faces and images. Factor 3: Emotional understanding (C, G) relates to the processing and resolution of emotional issues, such as understanding emotional changes and mixed emotions. Factor 4: Emotional management (D, H) involves controlling and managing one's own emotions and their interaction with others. Scoring for this test is relatively straightforward, based on consensus principles. However, this is also a limitation of the test, as there is no global or cultural standard for scoring.
