No. The McCall Field Campus is 1.3 miles (25 minute walk) from downtown McCall. There is a great bike path from the campus to town as well as public transportation.

Yes, and we have incorporated a course through the Wilderness Medicine Institute of the National Outdoor Leadership School (NOLS/WMI) as part of your initial training.

It is generally expected that students will arrive at MOSS with their own laptop computer. We have a wireless network with broadband internet connectivity along with a networked printer/copier.

Yes. If we offer you a position in the program and you accept, a $1,500 nonrefundable deposit is required within 30 days of acceptance in order to hold your seat in the program. If the deposit is not received within this timeframe, your seat will be forfeited to the next student on the waiting list. Once paid, the deposit is nonrefundable if you choose to relinquish your seat at a later time.

From Boise and points south, travel on State Highway 55 into downtown McCall. Several blocks before reaching Payette Lake, take a right turn onto Park Street. Park Street merges and turns into Thompson St. Follow Park/Thompson for 1/2 mile to stop sign. Take a left turn onto Davis Street. Follow Davis Street for 1.6 mile (through the Lick Creek Rd. intersection). You will have to stop at the PSP Kiosk. Say you are going to the UI Field Campus and they will let you through. Proceed till you see the Field Campus sign, turn left and follow road until you see the driveway into the McCall Field Campus (there is a sign on the left side of the road). Take a left into the McCall Campus driveway at the sign.

From points north, travel on State Highway 55 into downtown McCall. Highway 55 becomes Lake Street. At the intersection of Lake and 3rd Streets (both are technically still Highway 55), turn right onto 3rd. Travel south on 3rd for two blocks and take a left turn onto Park Street. Park Street merges and turns into Thompson St. Follow Park/Thompson for 1/2 mile to stop sign. Take a left turn onto Davis Street. Follow Davis Street for 1.6 mile (through the Lick Creek Rd. intersection). You will have to stop at the PSP Kiosk. Say you are going to the UI Field Campus and they will let you through. Proceed till you see the Field Campus sign; turn left follow road until you see the driveway into the McCall Field Campus (there is a sign on the left side of the road). Take a left into the McCall Campus driveway at the sign.

Its nice to have a bike for trips into town. Skis, kayaks, and other toys are fun (though keep in mind that there is limited storage space, so you'll want to choose wisely).

Fees cover the costs of instruction, room, board, and transportation.

Yes. Visit the University of Idaho Financial Aid website for more information.

The MOSS meal plan includes all meals we cook for MOSS K12 Residential Programs. If there is a school group on campus, you eat with the participants. No school group on campus, you create culinary delights for yourself. Check out the sample menu for an idea of what to expect, including a detailed list of breakfast, field lunch, dinner and salad bar options. While the menu can (and does) change according to the availability of ingredients, recipe tweaks and special requests, you can always count on tasty, kid-friendly meals with multiple fruit and vegetable options. If you have any food allergies or special food needs, the cooks will work with you to the best of their ability to meet your needs.

The graduate student lounge space is called the "Cook's Cabin" and also includes a full kitchen and a full bath.

The cabins have a small bathroom with a toilet and a shower. There is a bunk bed, a table/chairs, a small fridge, a kitchen sink area and a hotplate. There is a ceiling light and sometimes a lamp or two. The lamps tend to migrate around campus so if you have a favorite reading lamp, bring it along. All cabins have electricity and electric heat.

The yurts have a bunk bed, a table/chairs and a small fridge. There is a ceiling light and sometimes a lamp or two. All yurts have electricity and propane heat. The gender specific restroom is a short walk away. Please do not use appliances (i.e., hot water heaters, microwaves, toasters, etc.) in the yurts. You can still bring these items and use them in the Cook's Cabin (the grad kitchen and hang-out space).

Instructors in the past have found it useful to get a head start on learning some of the science content that we teach in the 5th and 6th grade program, especially if you are far removed from your last science class. Even if you are an ecology whiz, you might want to refresh yourself on these particular topics. We will cover everything in training, but we have to pack a lot of information into a short amount of time. We really recommend getting started now!

As an instructor at MOSS, you will need to be familiar with the following topics (at a minimum):

  • Watersheds
  • Qualitative and quantitative measures of water – pH, dissolved oxygen, turbidity, conductivity
  • Basic macroinvertebrate identification
  • Basic rangeland and forest plant identification
  • Soil – layers, structure, chemistry
  • Succession
  • Elements of fire – combustion, pyrolysis, the fire triangle
  • Fire ecology (the interaction and role of fire in an ecosystem)
  • Forest structure (layers)
  • Some bird identification is helpful
  • Some tracking skills are helpful
  • The basic steps of the scientific process of inquiry (“the scientific method”) and science process skills (basic and integrated)
  • A basic understanding of earth systems science, (lithosphere, hydrosphere, biosphere, and atmosphere) and interactions between them.

Yes, as long as your roommate is okay with it and there are not K-12 students on campus. Exceptions to this can be made on a case by case basis.

Field instructors live in either cabins or yurts, depending on their housing preference. A housing preference form is included in your paperwork packet. Cabins have their own bathroom, while yurt residents use the bathhouse.

A WFA/CPR course through the Wilderness Medicine Institute of the National Outdoor Leadership School (WMI of NOLS) will be held the weekend before MOSS training begins. The cost of the WFR/CPR is $230 and room/board will be provided. If you would like to get your WFA/CPR training that weekend, please contact Sacha Jackson and let her know that you will be joining us for the year.

Yes. We strongly encourage students to live on campus for at least the first fall semester, however. We are happy to accommodate individual needs on a case by case basis.

Unfortunately, we do not allow pets to live on campus.

Living at the U of I McCall Field Campus is an opportunity of a lifetime. The campus is located on Payette Lake with 600 feet of sandy beach, includes eight cabins, a classroom/office building, two staff cabins (duplexes), a dining hall, two large classroom yurts (one for MOSS students and one for field instructors), five small staff yurts and a bathhouse.

Unlike many graduate programs, field instructors at MOSS get to know each other very well by living and working together. Many students spend their time off with the other field instructors by the lake, biking and hiking in the mountains, attending concerts in town or having a campfire together. Students also enjoy spending time in nearby Ponderosa State Park. The MOSS community is very close-knit.

The campus is busy, but field instructors have some special places to have some quiet time, if they want. The area surrounding the staff cabins is off limits to MOSS students. Also, the beach is a quiet place that staff can go. The field instructor classroom yurt overlooking the lake is another great place to hang out, work on lesson plans or finish homework. The social atmosphere of the MOSS community is a highlight of the MOSS experience.

We recently remodeled the old "Cook's Cabin" to provide a common lounge space for our graduate students. It contains a full kitchen, a living area and a full bath.

Room and board costs are billed through the University of Idaho and will be billed as soon as you are registered for classes. You will receive a letter from the University of Idaho at whatever address you have indicated as your mailing address. Bills need to be paid according to the UI Fee Schedule. Typically, registrations are processed around the beginning of August.

The basic layout for a MOSS teaching week includes the following:

  • Monday: students arrive, introduction, team building
  • Tuesday: hydrology day*
  • Wednesday: terrestrial day*
  • Thursday: student led research project
  • Friday: closing program, students leave

*Half of the students will have terrestrial day on Tuesday, while the other students are participating in hydrology day, Wednesday, the students switch. All field instruction takes place in Ponderosa State Park (located within a 15-minute walk of the MOSS Field Campus).

Generally, field instructors work with their students from 8:00 am until 4:00 pm. Some nights, field instructors are needed for evening activities after a two hour break.

Monday, teachers begin with a team meeting. Instructors work together to get field notebooks, nametags, and the classroom setup. Instructors usually meet at 10:00 am, break for lunch, and finish up by early afternoon. The students usually arrive around 1:00 pm. After students arrive, field instructors facilitate a few large group activities, and then break up into their teams. Each group develops a team contract and discusses their expectations for the week. The rest of the day is spent getting to know the students and teaching some of the basics of the MOSS curriculum including Earth System Science and the scientific method. Field instructors are expected to eat dinner in the dining hall with students. Following dinner, teams meet again, and then participate in an evening activity together.

Tuesday, Wednesday, and Thursday the day starts bright and early with a 7:15 am team meeting. Field instructors meet together to go over scheduling for the day, as well as to discuss any student or chaperone issues that may have arisen. At 7:45 the chaperones will come in to discuss the day plan with you. At 8:00 am, field instructors meet with their students. Most of the day is spent in the field (9:00 am until 3:45 pm). Specific details of the MOSS schedule will be given during orientation.

The hydrology day content focuses on the watersheds. Students learn about the interactions between water and land, the water cycle, water quality measurements, and macro invertebrates. Teachers work with their students to build understanding through questioning rather than traditional lectures. Students have the opportunity to see the McCall area and gain an understanding of its watershed. Macroscopes, water chemistry kits, pH paper and other scientific tools are used to facilitate the learning process. On terrestrial day, students are provided with an opportunity to learn the basics of terrestrial ecosystems. Students learn to identify signs of succession, native and nonnative species, and forestry management practices. Using a matchstick forest, students are also able to explore fire behavior and the impacts of forest management.

For research day, field instructors help their students develop a project using the scientific method and science process skills. The research project is completed in Ponderosa State Park. Topics vary depending on the student’s interests. Some examples include: what types of fuels burn best, how does water temperature affect levels of dissolved oxygen, how does tree density vary between managed and unmanaged forests.

Friday, students present their research projects, complete a final evaluation and head home by 10:30 am. After the students leave, members of the teaching and academic teams clean up the MOSS campus in preparation for the next teaching week. Following lunch, all of the MOSS field instructors and staff participate in a weekly debriefing which includes highs and lows of the week, what could be improved, and other issues that arose during the week. Debriefing usually lasts around two hours, but field instructors are expected to be available until the meeting is finished on Friday. In past years, teachers have really enjoyed the opportunity to reflect each week with their fellow teachers.

The basic format for a teaching week is the same for all five weeks. Teachers generally try new activities to improve their lessons each week, but the content remains the same. Students are excited about being able to spend time learning outside and participate in team building activities. Teaching at MOSS is an unforgettable experience.

There are two thrift stores, one consignment shop and one outdoor gear consignment shop in McCall.

You get one week for Thanksgiving break, approximately three weeks for Winter break, and one week for Spring break. Additional personal or professional days may be arranged on a per case basis.

The main option for public transportation to McCall is the Northwest Trailways Bus Service. Call 1-800-366-3830 for information. It is also possible to get a taxi from the airport (~$100) or contact some other incoming students to ride share.

Most (but not all) weekends are free. We take a week off at Thanksgiving, 3 weeks for winter break, one week for spring break.

We strongly suggest that students not work outside of the MOSS academic program. The graduate program is very time intensive requiring nights and weekends to study, complete assignments and rest. We cannot prohibit you from working if you feel it is necessary. We will be very honest with students if we feel their outside work is interfering with their academic progress.

Tuition and fees will be billed to your student account twice throughout the academic year. The first half will be billed in August and the second half in January. Visit Student Accounts for details and deadlines.

Your deposit will be credited to your account at the close of the 10th day of classes. You must pay your bill or set-up a payment plan before the 1st day of classes, however. Below are your options:

  1. Pay the full balance and get the deposit refunded to you after the 10th day of class
  2. Pay the full balance MINUS the deposit. Once the deposit credits to your account you will have a $0 balance
  3. Set-up a payment plan and make the required first payment. After the 10th day of class, the deposit credit will show on your student account thus reducing the total amount you have to pay
