New banding results for secondary schools in Wales show an "encouraging" improvement among schools at the bottom of the scale, education minister Leighton Andrews said today.

Of the 219 secondary schools included in today's data, 72 schools have moved up at least one band, while 71 schools have fallen at least one band.

“I have made a clear commitment to raising standards and performance in schools in Wales, improving levels of literacy and numeracy and reducing the impact of poverty on educational attainment. Banding is at the heart of our school improvement agenda in Wales and we're committed to releasing this performance data year on year."

Mr Andrews said advances in results in core subjects of schools ranked in the lowest bands - four and five - represented a "significant achievement".

There are five bands, ranging from Band 1 - schools performing well - to Band 5 - schools which need to improve.

What Is the Role of Attainment Banding in Promoting Pupils’ Progress in Mathematics?

The definition of banding is dividing the year group into bands differentiated by ability. Within each band, the pupils are grouped depending on ability or size. Setting can be used to group pupils in bands according to their ability in a subject as defined by HM inspectors of schools (HM Inspectors of Schools, 1979). For this literature review, it will be assumed that setting is used within bands.

Ball (Ball, 1981) research found that banding resulted in an increase in behavioural issues which resulted in disruptions in lessons of moderate attainment groups as teachers found difficulty in maintaining control, meanwhile low attainment groups had less behavioural problems. The behavioural problems that teachers had with mixed attainment banding was because they were not differentiating between mixed attainment teaching and mixed attainment banding which influenced the link between behaviour and grouping rather than the teaching style. The mixed attainment banding teaching style required a different teaching syllabus to attainment banding to ensure that every pupil regardless of attainment levels feels their educational needs are met which was attained by the use of worksheets. Mixed attainment banding improved behaviour but the hierarchy of pupils’ attainment across the bands was the same as the attainment banding. However, as this research is more than 30 years old, it does not provide the full accurate differences between attainment banding mixed attainment banding.

In educatie lijkt dit te gelden:

attainment band = niveaugroep

Step 4 – Attainment

Fourth, we need to determine attainment towards goals. Very often, attainment is determined by calculating the total value of deals credited to each rep (or team). The sum is then compared to a quota or threshold. For example, if revenue is your valuation metric, attainment could be each rep’s total revenue. If the number of booked appointments is your metric, attainment could be each rep’s total count. Sales Cookie supports more exotic ways to determine attainment. For example, if you wanted attainment to be based on the average call duration of booked appointments, you could do this. Or if you wanted to rank reps based on profit (ex: sales contest), you could also do this.

Step 5 – Rewarding

Fifth, we need to calculate and assign payouts. Often, attainment will impact payouts. Many incentive plans have multiple attainment bands. Attainment bands can have different accelerators, bonuses, commission rates, etc. Sales Cookie can handle all those scenarios. Note that the rep who was credited with a sale isn’t necessarily the person payouts should be assigned to. For example, you could assign rewards to their managers. Or you could decide that payouts should be shared with team members. In some cases, rewards are global (ex: cash bonus). In other cases, rewards are per-transaction (ex: per-deal commission). Sales Cookie lets you calculate payouts in sophisticated ways using advanced formulas and scripts. You can even execute SQL queries, which run on a virtual set of sales transaction credited to each rep (or territory).

Attainment – Attainment represents achievement vs. a sales performance goal for a specific time period. Often, each rep’s attainment is measured using “credits” (see definition below). Typically, credits and attainment impacts commission amounts or rates.

Tiers – Many incentive plans measure attainment, and define nuanced payouts depending on attainment. Tiers define bands of attainment, each having associated rewards. Tiers can be cumulative (in which case lower attainment tiers will also have their rewards triggered), or non-cumulative (in which case only the highest attained tier counts). Also, each tier may pay commissions over all transactions, or only over in-band transactions. Example: “Our AE plan has 4 cumulative tiers – below 40% quota, 40-100% quota, 100-200% of quota, and 200+% quota”.

Hier een voorbeeld van een 'incentive plan' met meerdere 'attainment tiers' en bijbehorende extra beloningen:

This article is only applicable if your commission plan has multiple attainment tiers, each with a different payout. If your plan does NOT have tiers (ex: you pay commissions per-transaction with no required minimum), skip ahead.

Consider a sample incentive plan based on revenue, quotas, and 3 attainment tiers:

Tier A
Under 100% of quota = 6% of revenue

Tier B
100% - 150% of quota = 8% of revenue

Tier C
Above 150% of quota = 10% of revenue
