A Regents waiver is permission, granted by the NY State Board of Regents, to graduate HS students by performance-based (AKA portfolio) assessment. Students must do a minimum of four PBATs in core subjects (ELA, SS, Math, and Science), and their performance is evaluated according to a rubric created by the Performance Standards Consortium. Students may also complete additional PBATs in Spanish and Art/Music.

No. Definitely not. They require significant instruction and preparation, high-level reading, writing, thinking, revision, and presentation skills. They require students to demonstrate subject mastery that indicates readiness for college.
PBATs and the work that leads up to them prepare students for the tasks they will need to do in college: research, information gathering, application and analysis, presentation, and defense of individual thinking. Many students struggle in college because they cannot manage a college-level reading load, cannot write on a college level, and do not feel comfortable expressing themselves in academic discussions. PBATs develop all of these skills.
The student presents to a panel typically composed of the student&#;s PBAT mentor (the teacher who supervised the writing of the PBAT), a teacher who has had the student before, a teacher who may not have had the student before, a support staff member (school counselor, administrator, etc.), peers of the student whom s/he has invited, family members (optional), and/or an outside evaluator. There is a minimum of three adults on a student&#;s panel who are official panelists &#; any additional adults or panelists are requested to be silent supporters.
The Consortium is a coalition of high schools across New York State that has pioneered the creation of educational communities synonymous with active student learning, exemplary professional development and innovative curriculum and teaching strategies for 21st century students. Many of our schools and leaders have been nationally recognized through such honors as New American High Schools, 21st Century Schools, Blue Ribbon Schools of Excellence, and Compact for Learning Schools. Consortium schools have devised a system of assessment, which consists of eight components including alignment with state standards, professional development, external review, and formative and summative data. Consortium schools have documented how their work meets and exceeds New York State Regents standards through a system of rigorous commencement-level performance-based assessment tasks. Performance on these tasks is reflected on student transcripts and results are used for college admission. The tasks require students to demonstrate accomplishment in analytic thinking, reading comprehension, research writing skills, the application of mathematical computation and problem-solving skills, computer technology, the utilization of the scientific method in undertaking science research, appreciation of and performance skills in the arts, service learning and school to career skills. Experts external to the schools, from universities and the business world, participate in reviews of student work. The Performance Assessment Review Board, Inc., an external body of educators, test experts, researchers and members of the legal and business world, monitors the performance-based assessment system and systematically samples student work.&#; You can learn more about the Consortium at www.performanceassessment.org
^ James Baldwin and Humanities Prep, like BCS, are also Expeditionary Learning Schools.
Students who complete all the requirements as stated in the waiver get a NY State Regents Diploma. It looks just like any other Regents diploma.
The waiver states that our students must take the ELA Regents and get a minimum grade of 65. No other Regents are required. (Students who get a grade of 75 or above on the ELA Regents do not need to take remedial English at CUNY colleges. Those with grades below 75 must take remedial English if they go to a CUNY college.)

The harm caused by unrecyclable plastic to the environment is significant and widespread. According to a report by the World Economic Forum, there could be more plastic than fish in the ocean by if current trends continue to rise. Not only that, but plastic waste in the ocean harms marine life. It can equally enter the human food chain because fish and other aquatic organisms consume tiny particles known as microplastics. Considering that, one study estimates that people who eat seafood ingest up to 11,000 pieces of microplastic each year.
To combat this problem, there is a growing interest in eco-friendly alternatives to traditional plastics. One alternative is PBAT (PBAT's complete form is polybutylene adipate terephthalate), which refers to a biodegradable polymer from renewable resources like corn starch and vegetable oil. Let's explore what PBAT plastic is, what it offers, and how it works in various applications.
What Exactly Is PBAT Plastic?
PBAT, a random copolymer, is a biodegradable substance comprising a copolyester of adipic acid, 1,4-butanediol, and terephthalic acid (derived from dimethyl terephthalate). This material may also be called poly(butylene adipate-co-terephthalate), occasionally polybutyrate-adipate-terephthalate, or simply "polybutyrate." PBAT, or polybutylene adipate terephthalate, is marketed as a fully biodegradable substitute to low-density polyethylene and has similar properties, such as flexibility and resilience, making it suitable for applications like plastic bags and wraps.
What Are the Benefits of PBAT Plastic?
Here are some of the notable benefits offered by PBAT plastic:
ü Good Ductility: PBAT (polybutylene adipate terephthalate) is a type of biodegradable plastic known for its good ductility, which refers to a material's ability to deform under stress without breaking. PBAT has a relatively high elongation at break, which means it can stretch without breaking. For example, PBAT films can stretch up to 350% of their original length before breaking, and this property makes PBAT plastic ideal for flexible packaging applications, including food packaging or compostable bags.

ü Good Elongation at Break: PBAT has an excellent elongation at break, which means that it can stretch considerably before breaking. The elongation at break for PBAT can range from 100% to 700%. For instance, PBAT fibers may have an elongation at a break of around 200%, and this property makes PBAT plastic suitable for applications requiring high flexibility and stretchability, such as disposable gloves or stretch wrap.
ü Good Heat Resistance: PBAT has good heat resistance, meaning that it can withstand high temperatures without degrading or losing its physical properties. The melting temperature of PBAT is around 160-170°C, and its glass transition temperature is around -30°C, which makes PBAT plastic suitable for applications requiring high-temperature resistance, like microwaveable food containers or hot drink cups.
ü Excellent Biodegradability: One of the most significant benefits of PBAT plastic is its excellent biodegradability &#; PBAT is a biodegradable polyester that can decompose under aerobic and anaerobic conditions. The biodegradation rate of PBAT can vary depending on the environmental conditions, but it typically takes 60 to 120 days for PBAT to biodegrade in soil or compost completely. Meanwhile, this property helps PBAT plastic to become an ideal choice for applications that require sustainable and eco-friendly materials, incorporating single-use packaging or disposable cutlery.
How Does PBAT Work in Its Applications?
In this section, we will have a look at how PBAT plastic works in numerous applications:
1. Shopping & Express Bags
The production of shopping bags, express bags, and other forms of packaging that are intended to be used just once may be accomplished with the help of PBAT plastic or polybutylene adipate terephthalate plastic. Essentially, these bags are able to be composted once they have been used, meaning that they produce less waste and have less effect on the environment.
2. Packaging Films
PBAT may also be used in the production of many types of packaging films, some of which are utilized in the food, cosmetics, and pharmaceutical sectors. In addition to being able to shield objects from moisture and oxygen, these films are also biodegradable and may be composted.
3. Agricultural Films
The production of agricultural films, which are used to cover crops and shield them from both insects and severe weather, may be accomplished with the help of polybutylene adipate terephthalate plastic. These films may also be biodegradable and compostable, which will ultimately help cut down on the amount of trash produced by the agricultural sector.
4. 3D Printing Material
PBAT may be used as a filament in 3D printers, which enables the development of 3D-printed objects or products that serve the purpose of biodegradability and compostability. Eventually, these products have applications in many different fields, such as the packaging industry, the consumer products sector, and the medical supply sector, among others.
5. Disposable Tableware
The production of disposable tableware, such as plates, cups, and utensils, may be completed with the use of PBAT plastic. Since these goods may be composted after use and are biodegradable, they contribute to a reduction in waste in the food service business.
6. Disposable Medical Supplies
PBAT polymer or plastic may be used in the production of a variety of one-time-use medical products, including but not limited to gloves, gowns, and masks. Since these goods are compostable and biodegradable after they have been used, they help the healthcare sector save resources while simultaneously meeting rigorous safety and hygiene requirements.
