COLORADO COMMUNITY COLLEGE SYSTEM CAREER & TECHNICAL EDUCATION TECHNICAL STANDARDS REVISION & ACADEMIC ALIGNMENT PROCESS
Colorado’s 21st Century Career & Technical Education Programs have evolved beyond the historic perception of vocational education. They are Colorado’s best kept secret for:
• Relevant & rigorous learning
• Raising achievement among all students
• Strengthening Colorado’s workforce & economy
Colorado Career & Technical Education serves more than 116,000 Colorado secondary students annually through 1,200 programs in 160 school districts, 270 High Schools, 8 Technical Centers, 16 Community Colleges & 3 Technical Colleges. One of every three Colorado high school students gains valuable experiences by their enrollment in these programs.
ALIGNMENT REQUIRED BY SB 08-212
22-7-1005. Preschool through elementary and secondary education - aligned standards - adoption - revisions.
2(b): In developing the preschool through elementary and secondary education standards, the State Board shall also take into account any Career & Technical Education standards adopted by the State Board for Community Colleges and Occupational Education, created in Section 23-60-104, C.R.S., and, to the extent practicable, shall align the appropriate portions of the preschool through
elementary and secondary education standards with the Career and Technical standards. STANDARDS REVIEW AND ALIGNMENT PROCESS
Beginning in the fall of 2008, the Colorado Community College System conducted an intensive standards review and alignment process that involved:
NATIONAL BENCHMARK REVIEW
Colorado Career & Technical Education recently adopted the Career Cluster and Pathway Model endorsed by the United State Department of Education, Division of Adult and Technical Education. This model provided access to a national set of business and industry validated knowledge and skill statements for 16 of the 17 cluster areas. California and Ohio provided the comparative standards for the Energy cluster • Based on this review Colorado CTE has moved from program-specific to Cluster & Pathway based standards and outcomes
• In addition, we arrived at fewer, higher, clearer and more transferrable standards, expectations and outcomes.
COLORADO CONTENT TEAMS REVIEW
The review, benchmarking and adjusting of the Colorado Cluster and Pathway standards, expectations and outcomes was through the dedicated work of Content Teams comprised of secondary and postsecondary
alignments for math, science reading, writing and communication, social studies (including Personal Financial Literacy) and post secondary and workforce readiness (PWR.)
ACADEMIC ALIGNMENT REVIEW
In order to validate the alignment of the academic standards to the Career & Technical Education standards, subject matter experts in math, science, reading, writing and communication, and social studies were partnered with career & technical educators to determine if and when a true alignment existed.
CURRENT STATUS
• One set of aligned Essential skills to drive Postsecondary and Workforce Readiness inclusion in all Career & Technical Education programs.
• 52 pathways with validated academic alignments
• 12 pathways with revised standards ready for alignment (currently there are no approved programs in these pathways)
• 21 pathways where no secondary programming currently exists. Standards and alignments will be developed as programs emerge.
Colorado Career & Technical Education Standards Academic Alignment Reference System
The Career & Technical Education standards have been organized by Career Cluster (17) and Pathway (81). In addition, a set of “Essential Skills” was developed to ensure the Postsecondary and Workforce Readiness within any cluster or pathway. These workforce readiness skills are applicable to all career clusters and should form the basis of each CTE program.
Organization Essential Skills
There exists a common set of knowledge and skills that are applicable to all students regardless of which cluster or pathway they choose. This set of standards, is meant for inclusion in each program to enhance the development of postsecondary and workforce readiness skills.
Career Cluster
A Career Cluster is a grouping of occupations and broad industries based on commonalities. The 17 Career Clusters organize academic and occupational knowledge and skills into a coherent course sequence and identify pathways from secondary schools to two- and four-year colleges, graduate schools, and the workplace. Students learn in school about what they can do in the future. This connection to future goals motivates students to work harder and enroll in more rigorous courses.
Career Pathway
Pathways are sub-groupings of occupations/career specialties used as an organizing tool for curriculum design and instruction. Occupations/career specialties are grouped into Pathways based on the fact that they require a set of common knowledge and skills for career success.
Prepared Completer Competency
This level targets the “big ideas” in each pathway. These are the competencies that all students who complete a CTE pathway must master to ensure their success in a postsecondary and workforce setting. Prepared Completer Competencies will not usually be “course” specific but grow with the student’s progression through the sequence of courses.
Concept/Skill
The articulation of the concepts and skills that indicates a student is making progress toward being a prepared completer. They answer the question: What do students need to know and be able to do?
Evidence Outcome
The indication that a student is meeting an expectation at the mastery level. How do we know that a
Academic Alignments
Academic alignments, where appropriate in Math, Reading, Writing and Communication, Science and Social Studies (including Personal Financial Literacy) were defined by CTE and academic subject matter experts using the following criteria:
• It was a point where technical and academic content naturally collided;
• The student must demonstrate adequate proficiency with the academic standard to perform the technical skill; and
• It could be assessed for both academic and technical understanding.
Colorado’s CTE programs have had academic alignments dating back to the early 1990’s. While these alignments resulted in an increase in academic focus in CTE programs, the reality is that a true transformation in intentional teaching toward the academic standard was limited.
With these alignments comes a new expectation: If a CTE instructor is teaching a CTE concept that has an identified alignment, they must also be intentional about their instruction of the academic standard. CCCS will be providing professional development and instructional resources to assist with the successful
implementation of this new expectation. In addition, this expanded expectation will require increased collaboration between CTE and academic instructors to transform teaching and learning throughout each school.
For each set of Cluster and Pathway standards, the academic alignments have been included and are separated by academic area. CCCS chose to align at the “Evidence Outcome” level. The aligned academic evidence outcome follows the CTE evidence outcome to which it has been aligned. For a sample, see Illustration A.
The academic standard number used in the alignments matches the Colorado Department of Education standards numbering convention.

instructions built into the ROM of a microcomputer to start the computer when it is turned on
First-generation languages the earliest programmers wrote instructions in machine. when computers were first invented, this was the only type of programming language available. machine language instructions are written in binary (series of 0s and 1s)
FORTRAN (FORmula
TRANslation) the first widely used third-generation, high-level programming language. it was developed at IBM Corporation in the mid-1950s and has been enhanced many times since then. it is commonly used for mathematical, scientific, and engineering applications

Logical (boolean) field contains one of two values such as "yes"/"no" or "true"/"false" ; Example. "Money turned in to the league"
Machine dependent means that each computer had its own machine language, so a program written for a particular computer would not work on another type of computer
Machine independent third-generation instruction that might be converted into more than one machine-language instruction that is not tied to particular computers Machine language the binary (on/off) representation of computer instructions
Manual Data Processing processing data without a computer
Memory size of a computer the storage capacity of its RAM. Measured in kilobytes (K). a single kilobyte is 1,024 storage locations. one thousand kilobytes is equivalent to 1

Numeric field contain only numbers, a decimal point, a positive or negative sign Object program compilers and assemblers generate this machine language as output Object-oriented language when programming in this language, the programmer creates objects and
methods for working with the objects. one of the first object-oriented programming languages was Smalltalk, which was developed in the mid-1970s by Xerox Corporation. Example. C++
Operand describes the data used in the instruction
Operation Code machine language instructions that consist of the instruction to be executed Primary (main) storage
(memory)
stores the data and instructions (programs) needed by the computer Procedure-oriented
language in these languages, the emphasis of the program is on how to accomplish a task. the programmer writes the instructions as well as determines the order in which the computer should process the instructions. Example. FORTRAN, COBOL, BASIC, and C
Program specifications the specifications used by the programmer Program testing the only way to find logic errors
Programming Logic designing solutions to problems that will be solved by a computer RAM (random-access
memory) main memory. before a program's instructions can be carried out or executed by the computer, these instructions must be stored in RAM. Real (floating point) field refer to numeric fields that have decimal points such as 11.213 and -12.36.
can be single precision or double precision depending on the magnitude and accuracy required
Record how files are composed; Example1. each listing in a phone directory
represents a record (files are composed fo records); Example 2. a payroll file contains one record for each employee
erased when the power to the computer is turned off. the programmer has no control over what is stored in the ROM
Second-generation
language ... Secondary (external or
auxiliary) storage used as additional memory for the computer, is cheaper than primary storage because it does not have to be as fast. it is permanent in that turning off the computer does not erase secondary storage.
Software term used to describe computer programs
Source program the program written by the programmer which is the input to a compiler, interpreter, or assembler
Statement all programming languages consist of a set of these instructions and syntax rules for putting them together to make valid instructions
Subroutine (function or
