CSII in Texas most commonly refers to Computer Science II, a one-credit high school course in the Texas education system. It is part of the state’s career and technical education (CTE) curriculum, codified in the Texas Administrative Code under Section 127.790. Outside of education, CSII can also stand for Continuous Subcutaneous Insulin Infusion, a medical term for insulin pump therapy sometimes referenced in Texas Medicaid documentation. Here’s what you need to know about both meanings.
Computer Science II as a Texas High School Course
Computer Science II is an advanced programming course recommended for students in grades 10 through 12. To enroll, a student must have completed Algebra I and either Computer Science I or AP Computer Science Principles. Successful completion earns one high school credit.
The course goes well beyond introductory coding. Students work with object-oriented programming concepts like inheritance, encapsulation, and polymorphism. They learn to trace and compare sorting and search algorithms (such as linear search, binary search, selection sort, merge sort, and others) and measure algorithm efficiency using “big-O” notation. The curriculum also covers recursion, Boolean algebra including De Morgan’s Law, and working with data in decimal, binary, octal, and hexadecimal number systems.
What Students Learn in CSII
The Texas Administrative Code breaks the course into several skill areas that go beyond just writing code.
- Program design and problem solving: Students follow systematic processes to analyze and modify programs. They compare design methodologies like top-down, bottom-up, and black box approaches, and use abstract data types along with advanced data structures.
- Data management: Students process text files, manipulate data using string processing and casting, and work with one-dimensional and two-dimensional arrays as well as list objects. They also learn to differentiate between types of programming languages, from machine and assembly languages to high-level compiled, interpreted, and scripted languages.
- Collaboration and communication: Students work in software design teams, break problem statements into specific requirements, create development plans, and test solutions against both boundary and standard cases. They also develop presentations to communicate their work.
- Career readiness: The course includes identifying job and internship opportunities in computer science, examining the role of certifications and portfolios, and comparing university computer science programs. Students also practice technical reading and writing skills.
In practical terms, CSII prepares students for AP Computer Science A, college-level programming courses, or entry-level technical roles. It is a meaningful step up from Computer Science I, shifting the focus from basic programming logic to software design principles and algorithmic thinking.
How CSII Fits Into Texas Graduation Plans
Computer Science II counts as a CTE course and can fulfill elective credit requirements under Texas graduation plans. For students pursuing a STEM endorsement on their diploma, CSII fits naturally into a coherent sequence of computer science courses. Schools that offer the course typically place it after Computer Science I in a two- or three-year pathway that may also include AP Computer Science A or independent study in technology applications.
Not every Texas high school offers CSII. Availability depends on whether the district has a qualified instructor and enough student demand. If your school doesn’t offer it, ask a counselor whether it’s available through a neighboring district, a state-approved online provider, or a dual-credit arrangement with a community college.
CSII as Insulin Pump Therapy in Texas Medicaid
In medical contexts, CSII stands for Continuous Subcutaneous Insulin Infusion, the clinical term for insulin pump therapy. This meaning comes up in Texas when patients or providers deal with Texas Medicaid (managed through the Texas Medicaid and Healthcare Partnership, or TMHP) to get coverage for an insulin pump and related supplies.
Insulin pumps and their supplies generally require prior authorization before Texas Medicaid will cover them. That means your provider must submit a request to TMHP before delivering the device or supplies. Requests can be submitted by mail, fax, or through the TMHP electronic portal. The submission must include the patient’s name, Medicaid number, date of birth, the provider’s National Provider Identifier, and the specific procedure codes for the equipment being requested.
If any required information is missing or illegible, TMHP sends the request back. Providers then have 14 business days to correct and resubmit. In most cases, prior authorization must be approved before the service is provided. For patients in a retroactive eligibility period, authorization must be obtained within 95 days of the eligibility add date. For services on or after the add date, providers need authorization within 3 business days of the date of service.
If you or a family member uses an insulin pump and is covered by Texas Medicaid, the key takeaway is that your prescribing doctor’s office handles the prior authorization paperwork. Make sure your provider has your current Medicaid number and that all forms are signed with an electronic or wet signature, as stamped signatures are not accepted.
