The Department will establish the requirements for the endorsements. A school system shall notify each senior and the senior's parents or guardians on or before the end of February of the senior year if a student may not graduate. The notice shall explain: The reasons the student may not graduate; The options available to meet all graduation requirements; That a waiver of the Maryland Comprehensive Assessment graduation requirement may be one of the options, if the student meets the criteria set forth in §§C and E of this regulation; The waiver process and timeline; and That parents or guardians may submit information in writing to the principal concerning eligibility of their child for the waiver. On or before the end of February, the principal shall report to the local superintendent the name and student identification number of each student identified in the February notice. On or before April 1, the school system shall identify each student who may fail to graduate because the student has taken none of the required Maryland Comprehensive Assessments. On or before April 1, the principal shall report to the local superintendent the name and student identification number of each student identified as meeting the criteria in §C of this regulation. By April 1, for each senior identified in §C of this regulation, the school principal shall consider whether to recommend to the local superintendent a waiver of the Maryland Comprehensive Assessment graduation requirements that the student has not fulfilled to date if: The student has or is expected to meet all the other graduation requirements; and The student is prevented from meeting the Maryland Comprehensive Assessment graduation requirements because: Of a decision made by the local school system concerning the provision of appropriate assistance as required by Regulation .06C of this chapter; The student experienced a special, extraordinary, or extenuating circumstance or combination of circumstances preceding the administration of the most recent Maryland Comprehensive Assessment, such as a recent death in the immediate family, a serious or prolonged illness or pregnancy with medical complications, an accident causing serious injury, or a destructive house fire; The student moved to the United States in the junior or senior year and the student is literate in the student's native language but not literate in English; or The student moved to Maryland in the senior year. On or about April 1, the principal shall notify the student and the student's parents or guardians that the student is being considered for a waiver of the Maryland Comprehensive Assessment graduation requirements that the student has not fulfilled to date. The notice shall explain the waiver decision-making process. On or before May 1, the principal of the high school shall make a Maryland Comprehensive Assessment waiver recommendation to the local superintendent for each student who meets the criteria set forth in §E of this regulation with the participation of: The student's IEP team, if the student is a student with disabilities; The English Language Learner staff, if the student is an English Language Learner; Other school personnel; or One or more of them. The principal shall explain the reason for each recommendation under §G of this regulation, whether the recommendation is to grant or deny the waiver. The local superintendent shall review each recommendation and shall: Grant or deny the waiver; Promptly notify the student and the student's parent or guardian of the decision; and If the waiver is granted, include in the notification the local procedures and requirements that must be met for a diploma to be awarded. The superintendent's decision in this matter is not appealable to the local board of education, but may be appealed to the State Superintendent of Schools. A student or the student's parents or guardians may appeal the waiver denial to the State Superintendent by sending a written appeal letter explaining why the waiver denial was an arbitrary or unreasonable decision. The State Superintendent may affirm or reverse the local superintendent's decision and shall inform the student, the student's parents or guardians, the local superintendent, and the State Board in writing of the decision. The decision of the State Superintendent may be appealed to the circuit court pursuant to Maryland Rules 7-201, et seq. On appeal: If the State Superintendent has reversed the local superintendent's decision to deny the Maryland Comprehensive Assessment waiver and the local school system appeals that decision, the State Superintendent shall defend the decision on appeal; or If the State Superintendent has affirmed the local superintendent's decision and the aggrieved student appeals, the local superintendent shall defend the State Superintendent's decision on appeal. By August 1, the local superintendent shall send a report to the State Superintendent or the State Superintendent's designee on waiver decisions rendered under this regulation. Nothing in this regulation is intended to establish any right to participate in the graduation ceremony while an appeal is pending. Participation in the graduation ceremony remains at the discretion of the local superintendent. In recognition of the fact that 4-year enrollment in a public high school may not serve the best interests of some students, the alternatives in §§B and C of this regulation shall be made available. Early College Admission Program. A student may receive a Maryland High School Diploma through acceptance in the early college admission program, if: The student is accepted for early admission to an accredited college before high school graduation; All Maryland Comprehensive Assessments and student service requirements have been met; A written request by the student and parent or guardian is made to and approved by the local superintendent of schools certifying the early admission acceptance; The student's program for the first year of college is approved by the local superintendent of schools if this program is included toward the issuance of a diploma; and At the conclusion of the program or after 1 year, a written request for a Maryland High School Diploma is submitted to the superintendent together with a transcript or letter from the college to the high school principal indicating that the student has successfully completed a year of college work.

An alternative plan may include a waiver of the fourth year enrollment requirement if all credit, assessments, and student service requirements are met and if the local superintendent of schools or designee determines that the waiver is in the best interest of the student. Procedures for implementing these alternative programs leading to high school diplomas are as follows: Development and approval of a curricular plan which assures that the content of the specified credits is included and the standards for graduation are met pursuant to the requirements of this chapter with the plan containing a program description, performance requirements, and evaluation procedures; and The local superintendent of schools is responsible for approving any plan and shall notify the State Superintendent of Schools once approval has been given. Length of School Year. Maryland public high schools shall be open for at least 180 school days and a minimum of 1,170 school hours during a 10-month period in each school year. Graduation Requirements for Transfer Students. Attendance Requirements. To receive a diploma, a student shall be in attendance at a Maryland public high school one full semester immediately preceding graduation in addition to meeting the other diploma requirements. In cases where this requirement creates an undue hardship for a student transferring to or from a Maryland nonpublic school or from an out-of-State school and wishing to receive a Maryland high school diploma, the local superintendent of schools may waive the one full semester attendance requirement. Exception shall be made for a student with disabilities in a State-approved nonpublic program. Students transferring from one Maryland public high school to another during the second semester of their senior year and meeting all requirements for graduation shall be given the option of graduating from either high school by agreement of the local superintendent of schools or the respective local superintendents when more than one local school system is involved. Maryland Comprehensive Assessment Exemption Requirements. A student who transfers from a nonpublic school or a school out of State is exempt from one or more of the Maryland Comprehensive Assessments if, consistent with local school system policy and procedure, the local superintendent determines that the course taken is aligned with the relevant Maryland Comprehensive Assessment and awards the student credit for taking any of the courses aligned with the Maryland Comprehensive Assessments, that is, algebra, science, English, or government, or all of these, in accordance with the principles set forth in §B(2)(c) of this regulation. A student who transfers from a nonpublic school or a school out of State and has not received credit for algebra but has demonstrated mastery of the Maryland College and Career Ready Standards for algebra either through an evaluation or successful completion of subsequent mathematics courses for which algebra is a prerequisite is exempt from the Maryland Comprehensive Assessment for algebra. To award credit for taking any of the courses aligned with the Maryland Comprehensive Assessments, that is, algebra, science, English, or government, a principal shall determine through the following considerations whether the transfer student demonstrates subject matter knowledge aligned with the content standards for the subject: Administration of standardized tests and examinations; Observation of the student in the classroom; Use of interviews that are focused around the student's demonstration of course content knowledge and performance levels; and Inspection of transcripts, report cards, and other documentation. A student who transfers from a nonpublic school or from a school out of State into a local school system after the first semester of their senior year is exempt from the Maryland Comprehensive Assessment Requirements. The exemption provided in §B(2)(d) of this regulation does not apply to a student with disabilities in a State-approved nonpublic program. Local Graduation Requirements. A student who enters a local school system in their senior year shall be granted a waiver from locally established graduation requirements unless the student chooses to fulfill the requirements. A student in foster care or a homeless student who enters a local school system in their junior year shall be granted a waiver from locally established graduation requirements unless the local school system makes a finding that the student is reasonably able to complete the locally established graduation requirements in time to graduate from high school. Unavailability of Official Transcript. If the transcript of record is not available, a local superintendent of schools or designee shall determine the appropriate placement of the student within the high school program by an evaluation of the student that shall include one or more of the following: Administration of standardized tests and examination; Observation of the student in a classroom setting; Use of interviews that are focused around the student's demonstration of course content knowledge and performance levels; Inspection of report cards and other documentation.
