High School


High School Curriculum An American curriculum with an international perspective.
High School courses are primarily college preparatory with AP courses offered in Grade 11 and Grade 12. Maximum class size is 25 students.  The focus is on the educational needs of the international student in preparation for university-level education anywhere in the world.  The high school diploma is awarded to students upon completion of all requirements for graduation.  NIS offers a wide range of elective courses including: Music,  Art, Web Design, PE, Sports Leadership, Journalism, Thai, French, Spanish, Chinese, and Dance.


The Advanced Placement (AP) program is a curriculum in the United States sponsored by the College Board which offers standardized courses to high school students that are generally recognized to be equivalent to undergraduate courses in college. Participating colleges grant credit to students who obtained high enough scores on the exams to qualify.

AP classes will be offered for Grade12:

AP Biology
AP Chemistry
AP Calculus
AP Psychology
AP Economics

AP Studio Art Drawing and AP Studio Art 2- D design.

Chewing gum

Chewing gum is not particularly healthy, when left on paths, tables and chairs gum is unhygienic and unpleasant. Also if chewed in class while speaking pronunciation is difficult to understand: in many cultures chewing gum is seen as impolite.

In accordance with school policies which state that students and teachers must demonstrate respect for each other and the school environment, we would like to inform the NIS community that chewing gum is not permitted on campus.

Nakornpayap International School Driving policy

The law in Thailand clearly states that to hold a valid motorbike license the rider must be 16 years of age, the rider is also obliged by law to wear a helmet at all times when riding on the road.

Likewise the law states that to hold a valid license to drive a car the driver must be 18 years of age and is obliged to wear a seatbelt at all times when driving on the public highway.

In line with the other international schools in the city NIS would like to state that in the interests of safety from September 1st 2011 no unlicensed driver will be allowed to bring their vehicle on school premises or to carry passengers. Students arriving at school will be asked to show their license, if they do not hold a valid license, then they will not be permitted to use the school parking facilities. Motorbike riders must wear a helmet.

NIS endeavors to foster a positive image in the wider Chiang Mai community; however this reputation may be seriously damaged by negative behavior of its faculty members. Allowing underage drivers in the school not only endangers the faculty, but also sets a bad example that flaunting the law is permissible. The school does not condone this behavior. We seriously hope that parents and guardians will support this move to improve the safety standards of the school.

Personal Possessions

Students should not bring large amounts of money or valuable items to school. Cell phones are not needed at school, and not allowed to be used in the classroom. If such items are brought to school, they should be kept in the possession of the owner at all times, locked in their locker, or left in the office. The school cannot accept responsibility for lost, stolen, or damaged items.

Student Behavior Code

At NIS we expect students to use their good common sense, and to avoid impolite or dangerous behavior. We reinforce the importance of self-esteem and mutual respect. Students are expected to have both positive attitudes and appropriate behavior at school, to act responsibly themselves and to be considerate of classmates, other students, teachers and staff. The purpose of any code of behavior should be to ensure an environment in which a person can feel safe and secure, and know that their rights will be respected so that they can fully achieve their potential. The rights of the
individual have to be balanced with the rights of others, and only with respect for ourselves and others is this possible. To achieve this nurturing environment, NIS has weighed individual’s rights, the purpose of the school, the educational process, and Thai law into the creation of the behavioral code. With rights come obligations. The main obligation is for us to take responsibility for our own decisions and their consequences. You will be held responsible for only the things that you do or fail to do. What others do or do not do is of little importance in determining whether or not you have accepted your responsibilities as a part of the NIS community. If you choose to follow a bad example set by a few, you will be held responsible for your actions and your actions only. NIS has been very fortunate over the years in having decent students that the NIS community as a whole can be proud of. There has been relatively little need to enforce the Behavior Code due to the students taking responsibility for themselves and respecting others. It is not possible to list all situations that might arise. The general rule to work from is to ask the question “Is this behavior good for me and others in the long run?” If the answer is no to either part, then it is probably best not to do it. The following are some behaviors, but not limited to these, that can lead to disciplinary actions including suspension and/or non-re-enrollment:

• Bullying or harassing behavior (including Cyberbullying).
• Fighting
• Possession of a dangerous object.
• Possession of Toy Weapons.
• Causing or attempting to cause damage to school or private property.
• Stealing or attempting to steal school or private property.
• Possession of alcohol, drugs, or drug paraphernalia.
• Attempting to sell drugs or other controlled substances.
• Willfully defying the valid authority of school personnel
• Cheating
• Misuse of school resources.
• Possession or use of Tobacco products.
• Being under the influence of alcohol, drugs, or other controlled substances at school or school sponsored events.
• The use of profanity of vulgar language.
• Disrespect of teachers or staff.
• Not following the dress code (high school only).

Displays of Affection

NIS has a wide range of ages, cultures, and religions represented at the school. Public displays of affection, beyond holding hands, are not appropriate. Physical contact such as kissing and groping are not appropriate conduct at school. If you are unsure whether a behavior is one for public display or private, it is best to keep it private. Parents will be contacted and disciplinary action taken for violations of this policy.

Smoking Policy

The school recognizes the serious health risk posed by smoking as well as its both psychologically and physically addictive nature. In response to the health risks the Thai government has made smoking on school grounds illegal, with large fines given to both the person caught smoking and the school where the incident occurs. An additional concern of the school is that younger students who observe the older students that they respect smoking are given the faulty message that the behavior is okay. Due to this the students who smoke become a harmful role model for the younger students. Given the indisputable life threatening health concerns for the student and the other factors smoking is banned.

Cellular Phones

The use of cellular phones during class time, in any way or for any reason, is not allowed. They must be shut off, and kept out of sight while class is in session. If this is not followed, teachers will confiscate the equipment, and it will be returned to the student at the end of the day. In the case of an emergency, parents may call the school’s office and their child will be brought to the phone.

School Bus Conduct

Using a school bus is a privilege, not a right. The school bus driver is responsible for your safety. Following the drivers instructions and good behavior are expected at all times. Continued poor conduct or serious misbehavior shall be sufficient reason for a student to be denied the use of school transportation.

Matches, Lighters, and Fireworks

Matches, Lighters, or any flammable objects are not allowed on campus. If found, these items will be confiscated and disciplinary measures taken.


Gambling of any kind is not allowed on campus.

Card Playing

Card Playing has long been an enjoyable way for students to pass time with their friends. There are benefits to math and reasoning skills that can be obtained depending on the type of games being played. Card playing during free time is allowed, however, if any form of gambling is connected to this, the cards will be confiscated and disciplinary measures taken.
