Often times, teachers have standards that are relevant for an entire semester or year. This doesn't always fit neatly into JumpRope's concept of Units, though it can help to understand units in the context of mastery as described in this article. The crux of the issue is that some standards are content-based, and thus typically taught and assessed in a discrete time period, while others are skill-based standards (such as "I can make a concise argument while writing...") that may be assessed a number of times over the course of a year or student career.
Our recommendation is to redefine your concept of "unit" as a "collection of similar standards." In doing so, you become intellectually free to create a unit titled "Long-term Standards" or something similar and to set the dates to the entire term or year. In this unit, write any and all of your long-term standards. Then, use the technique described in this document to align assessments from any of your units to these long-term standards. On reports, these long-term standards will show up in a special section that grows as you add evidence (more scores) over the course of the year.
Until you assess a standard for a student for the first time, the standard will not show up on their Progress Report. Because of this, you can go ahead and plan way ahead with your long-term standards without worrying about affecting the student's grade prior to the point that you actually teach it. Assuming that the start and end date on the unit last the entire year (or, at least, through multiple terms), the standards and assessments within that unit will be included in all reports for both terms. Thus, for example, your second term reports will include the long term standards and scores even from the first term, effectively allowing you to score the same standards across the entire year (long term standards)!
