4. What are the eligibility requirements for organizations to participate in the Program?

Completing the Participating Host Employer Application Form does not guarantee or entitle your organization to receive internship funds. In order for your organization to gain approval to participate, your organization must:

  • Be an eligible clean energy employer. For the purposes of the Program, MassCEC defines a clean energy employer as “an employer engaged in whole or in part in goods and services, or advanced and applied technologies that significantly reduce or eliminate the use of energy from non-renewable sources, including, but not limited to: energy efficiency; demand response; energy conservation and those technologies powered in whole or in part by the sun, wind, water, biomass, alcohol, wood, fuel cells, any renewable, non-depletable, or recyclable fuel.” MassCEC in its sole discretion makes the determination of whether an employer is a clean energy employer.
  • Be registered to do business in Massachusetts. If you are unsure if your business is registered to do business in Massachusetts, please consult the Secretary of the Commonwealth’s Corporate Database at the Commonwealth’s Corporations Division.
  • Provide a meaningful internship (as defined in the General Terms and Conditions).
  • Provide adequate proof that your organization is able to pay your intern(s) and all associated costs associated with employment.
  • Successfully demonstrate that your organization has a physical presence in Massachusetts.
  • Not be an academic or government entity.
  • Be in good standing with MassCEC. The Host Employer must have submitted all paperwork relating to any prior internship complete including the mandatory final survey, which has been received and approved by MassCEC.


5. Does MassCEC offer priority funding for certain subsectors?

MassCEC offers funding carve outs for the following subsectors:

  • Spring 2022: Thirty (30) reserved spots for students living in Gateway Cities and/or employers with an office in a Gateway City.
  • The reserved funding will be allocated on a first-come, first-served basis until the reserved spots are filled. Employers are still required to meet the other criteria listed above.
  • Once the reserved funding is fully allocated, the remaining funding will be allocated on a first-come, first-served basis.

6. Can Government or Academic Institutions Apply to the Internship Program?

Government and academic institutions cannot receive funding from MassCEC. However, they may use the database to identify potential interns. Contact for details.


7. How many interns may an organization employ?

Host Employers are allowed to select up to three (3) interns if one (1) of the three (3) interns attend a community college. Two (2) interns are permitted if neither attends a community college. Each intern must be approved individually. Funding for one (1) intern does not entitle you to funding for a second or third.


There is also a restriction on Related Party Organizations as defined below. If your organization owns other eligible organizations, or if your organization is owned by another, you are only allowed a maximum of three (3) subsidized interns for ALL Related Party Organizations.


Related Party Organizations are defined as organizations having common ownership and/or management personnel (including but not limited to the Chief Executive Officer, Chief Financial Officer, or Chief Operating Officer). Related Party Organizations are also considered to be related if at any time one (1) organization has the ability to Control (as defined below) the other organization or exercise influence over the other organization in making financial and/or operating decisions. Control is defined as:

  1. Ownership, directly or indirectly, of more than one half of the voting power of an organization; or
  2. Control of the composition of the board of directors, or other governing body of accompany organization; or
  3. A substantial interest in voting power and the power to direct the financial and/or operating policies of the organization.

Please be aware that MassCEC will not accept any documents submitted by any entity that is not the primary participating Host Employer.


8. How long can an intern stay at my organization?

An intern will be subsidized for one (1) session of work in one (1) calendar year. An intern may stay on after the conclusion of a session but will not continue to be subsidized by MassCEC.


9. Can we hire an intern from a previous session and be eligible for MassCEC reimbursement?

 MassCEC will only provide reimbursement if the intern is hired in a different calendar year, and not a subsequent session. For example, an employer may take on the same individual once per year in the same session (i.e., Summer 2020 and Summer 2021) OR twice per year in nonconsecutive sessions (i.e., Spring 2021 and Fall 2021). Additionally, an individual will not be eligible to participate at the same Host Employer if they continue to work or volunteer for you in between sessions in an amount greater than five (5) hours/week on average.


Current or very recent employees are not eligible to participate with you as an intern under the Program unless they have been working for the Host Employer less than six (6) weeks leading up to the session start date.


10. What are the eligibility requirements for prospective interns?

Students will be required to meet the following eligibility requirements:


1. Must attend, or have attended:

  1. A college or university located in Massachusetts; or
  2. A college or university outside of Massachusetts, only if the student is a Massachusetts resident and is able to present proof of residency; and 

2. Must meet one (1) of the following: 

  1. Students must have completed or will complete at least their freshman year of college (24 credits), the semester before the internship, or have graduated within the past calendar year;

Certain individuals are not eligible to participate in the Program:

  1. Law School students, Ph. D. candidates, or students who have been previously enrolled or matriculated in a Ph.D. program, are not eligible to participate in the Program.
  2. Full or part-time employees, both those who have received compensation as well as volunteers, are not eligible to participate in the Program at their current employers.
  3. Any full-time employee or existing intern that has been on payroll for greater than twelve (12) weeks at a Host Employer or has been continuously working at the Host Employer since their last participating session.


11. I’ve selected my student intern(s). Why do you need to conduct an eligibility check? I thought since they are in the database you had already been in touch with them.

MassCEC does not provide an eligibility check on interns before the check is specifically requested by a potential employer due to the large number of student applications we receive every session.


12. Is there a deadline for submitting signed offer letters to MassCEC?

All signed offer letters must be received by MassCEC no later than February 1, 2022.


13. What are a Host Employer’s contractual obligations?

Host Employers will be required to accept the General Terms and Conditions of the Program when applying. Host employers must also acknowledge the Award Letter with MassCEC. There is no explicit or implicit commitment on the part of any Host Employer to provide future employment for any intern.


By participating in the Program, the Host Employer and MassCEC do not form a partnership, employment relationship, joint venture, or principal and agent relationship. At no time is any Intern deemed or otherwise considered to be an employee, intern, contractor, subcontractor, or agent of MassCEC for any purpose. The terms and conditions of the Internship shall be set by an intern and the Host Employer and MassCEC shall have no responsibility, liability or oversight authority whatsoever with respect to Intern or the Internship. The Host Employer and its agents, employees, and Interns may not hold themselves out as MassCEC employees and shall not be deemed an employee of MassCEC for any purpose.


14. The Cleantech Industry is really competitive. I’d like to have my intern sign a non-compete agreement. Is there a policy for non-compete agreements?


Host Employers are not permitted to require or request that an intern sign a non-compete agreement. Host Employers are permitted to use non-disclosure or confidentiality agreement to protect any sensitive information.


15. My intern left mid internship. Can I still hire someone?

If a hired intern terminates employment during the internship, the Host Employer has until three (3) weeks after the start date referenced in the initial offer letter to hire a new intern. After the three-week window has passed, the Host Employer’s funding will be awarded to a company on the waitlist. New interns must be approved by MassCEC.


16. How much can I pay my intern?

The minimum wage for the Program is $15/hr. and MassCEC will reimburse up to $16/hr. MassCEC will only reimburse a Host Employer up to the cap of $3,840/intern in the fall or spring sessions and $7,680/intern in the summer session. Failure to pay an intern $15/hr. will result in your company being banned from the Program.


17. I’m a small organization and I don’t have a payroll system. What should I do?

If you are a smaller-sized organization and need assistance with your payroll services, please review the resource list below. Please note, without adequate proof of payment of the internship’s wages and taxes in the form of paycheck stubs and/or a payroll summary, reimbursement will not be issued to your organization. MassCEC will not reimburse a Host Employer for the costs of using a payroll service. Below are some examples of payroll services that are acceptable:


18. Can I hire a relative?

Host Employers are not allowed to hire Intern(s) if the intern is the spouse, child, grandchild, sibling, niece, nephew, or spouse of a child, grandchild, sibling, niece, or nephew of ANY employee of the Host Employer.
